5 Ways to Simplify Your Life and be Happy

5 Ways to Simplify Your Life and be Happy The Top 5 Ways to Live Life Simply and Happily The Top 5 Ways to Live Life Simply and Happily In an age where we are constantly adding more and more to our daily lives, i.e. stuff, and where we are told that stuff actually matters, it is worthwhile to sit down and think about what you really need to live simply and happily. The transcendentalist philosophers like Emerson and Thoreau believed that a connection with nature, a roof over your head, and adequate simple food was really all you needed to live a good life. Below are 5 ways to simplify your life and be happy. Complain Less Complaining can feel good, but it is often counterproductive. The reason that reducing the amount you complain is a good first step to simplifying things is because it increases the feelings of control that you have. When our lives begin to feel out of control, that is when stress and anxiety take over. This is a very easy step towards simplicity and happiness. Dont be Afraid to Say No Many people find themselves stressed and unhappy because they feel compelled to say yes to everything and everyone. The fear of disappointing people close, or important to us, often forces us to do things that dont truly make us happy. The act of considering how you feel about something, whether its a party, date, or an event and making your decision based on that will help simplify your life. It will do so by eliminating wastage of your time, and maximizing your enjoyable experiences. Pay Less Attention to the Media The media can be energy vampires. That means they suck up a large amount of your time without really giving you anything in return. One of the biggest ways by which people over complicate their lives is spending too much time thinking about the future, or the past. This kind of thinking is exactly what too much media encourages. Cap your daily and weekly media consumption and spend more time living in the moment to maximize happiness. Learn to Appreciate What you Have This is an old cliche, but people who understand what it means keep saying it because its true. If you are someone who is attending university, has a roof over their head, enough food to eat and is receiving a life altering education, you are better off than the majority of people on this planet. Be appreciative of the good things in your life and spend less time wanting, or lusting after things you dont need. Let simple living, and gratitude guide you to happiness. Eliminate Toxic People This is a skill that people often dont learn until it is too late, but being able to avoid, and cut out people who make your life more stressful, and less happy is a necessity. Friendship and love is incredibly important, but that doesnt mean you need to lie to yourself if when it doesnt exist. Dont let toxic, or negative people slow your growth. Simply move on and realize that it is the quality of your interpersonal relationships that counts, not the quantity. Living simply, guided by simple, powerful principles is the best route to happiness. Acquiring more “stuff” and being obsessed with what is going on in the world around you, especially the lives of your peers is not healthy. We spend so much time worrying about making a good impression and doing what other people want us to do, that we eventually forget to spend time on our own growth and development. Keep in mind the above 5 tips to simplify your life and live happily and you will quickly find that there is a lot to get out of life by simply cutting out the unnecessary.

The Production Of Production Activities - 1721 Words

Production Activities This section is an overview of the demands and tests associated with the integrity of well during production from and injection to a reservoir. The process begins after the well construction/well intervention organization has handed the well over to the production organization and concludes with a handover back to drilling and well organization for intervention, work-over or abandonment. Well integrity during this phase is used to keep hydrocarbons from the pay zone inside the well and by protecting it from leaking off to contaminating groundwater for environmental purposes. Well barriers are an envelope of one or several dependent barrier elements preventing fluids or gases from flowing unintentionally from the formation to the surface and are designed and used to prevent leakages and reduce the risk associated with drilling, production and intervention activities. The main functions of a well barrier are to prevent any major hydrocarbon leakage(s) from the well to the external environment during normal production or well operations and to shut in the well on direct command during an emergency shutdown situation and thereby prevent hydrocarbons from flowing from the well out. During production, a perfectly reliable well barrier element(s) is paramount to containing the hydrocarbons inside the well. Well barrier elements are several objects that prevent formation fluids from flowing inside the well.

Case Study 2001 Recession - 1278 Words

Ashley Alaniz ECON1301 Mr. Armstrong 06 November 2014 CASE STUDY: 2001 RECESSION ANALYSIS Beginning in March 2001, America soon fell into another recession that lasted eight months and ended in November of that same year. 2001 also happened to be the year 9/11 occurred which fueled the low confidence in the economic industry. The decline in services and employment after the attack made it inevitable that there is a recession underway. The recession of 2001 came during the introduction to the new electronic age when the technology industry was in full effect but little did the economy know that would play a major role in its downfall. The main factor that contributed to the recession was the collapse of the dotcom bubble, the rise of the technology industry and the new trend of internet websites. Many of these companies engaged in daring business practices with the hopes of dominating the market. Most used the practice of growth over profit, with the idea that if they built up their customer base, their profits would rise as well. As a result, the stock price of many high tech companies started to rise. This led to a lot of investors’ money going to any kind of high tech company, whether or not they were showing profits, and unfortunately many of these companies failed when the bubble finally burst. The loss of consumer faith in the tech industry also took a hit on earnings for technology ventures. The market also took a major downturn in the event of the terroristShow MoreRelatedJohn Moody Case Study Essay1318 Words   |  6 Pagesaround the Organization?

Role of Technology

Question: As our technology continues to change so rapidly, do our expectations change? Do we expect more now? What pressure does this, in turn, place on those developing technological solutions? Will this eventually affect such things as testing periods (for new technologies) and patent life? Answer: The changes in technology have made the daily life easier. As such, this has increased the expectations of the common public. The expectations change with the innovation in technology. This shall result in the increase in the expectations of consumers. Mom (2012) mentioned that this has an enormous pressure on professionals who are developing technological solutions. These professionals shall have to deal with the pressure of meeting the expectations of the client. However, such pressure shall not likely to affect testing period of new technologies as well as the patent life (Shanmugam et al. 2014).Such manufacturing processes would be executed as per the organizational guidelines to produce superior products for the consumers.

Aircraft Propeller Essays - Aerodynamics, Propellers, Blade Pitch

Aircraft Propeller The aircraft propeller looks like a simple mechanism to the uneducated individual. To the educated, an aircraft propeller represents the highest sophistication in aerodynamics, mechanical engineering and structural design. This report will touch on the history of the propeller, from early pioneers/experiments, advancement during/after the war, all the way up to current applications of the propeller. The creation of the propeller can be traced back to Leonardo da Vinci. Da Vinci's "helical screw" helicopter is believed to be the ancestor of the air propeller and the helicopter rotor. The first idea of a propulsive airscrew, however, belongs to J.P. Paucton, a French mathematician. Paucton envisioned a flying machine that had two airscrews, one for propulsion and the other for sustaining flight. The idea of using an airscrew for propulsion was utilized during the late 1700's to early 1800's. Only after experimentation did the inventors conclude that more propulsive power could be obtained by merely straightening out the surface of the airscrew blades. Attempts to utilize the "straight blade" propeller were made by balloonists. These contraptions were quite strange and hardly fulfilled their purpose of actually propelling the balloon. The basic propeller had evolved from the simple concepts of da Vinci, and was slowly becoming an effective means of aerial propulsion. To reach the next plateau of flight an increased knowledge of the propeller would be needed, and the mysteries of the propeller and mechanical power would need to be solved. These substantial tasks remained for aviation's pioneers to tackle during the 19th century. Throughout the 19th century, aviation pioneers explored and tinkered with the concepts of flight to design a viable airship. Some pioneers tried to transform the balloons into navigable cigar shaped airships by experimenting with sails, propellers, and paddlewheels but all produced limited results. Other experimenters, who were convinced that man flight should have wings, worked to establish basic principles in aerodynamics, flight stability and control, as well as propulsion. Controlled mechanical flight came on August 9, 1884. Charles Renard and A.C. Krebs flew the airship "La France" on a closed circuit from Chalais-Meudon to Villacoublay and back in 23 minutes. The airship "La France" was powered by a 9 horsepower electric motor that drove a 23ft diameter propeller and reached a speed of 14.5 mph. This flight was the birth of the dirigible, a steerable, lighter-than-air ship with adequate propulsion. Another important milestone in aviation, was the understanding of aerodynamics. Sir George Cayley, a British theorist, was acclaimed as the father of aerodynamics. He established a solid foundation of aerodynamic principles that were essential to the success of other pioneers. In 1875, Thomas Moy created a large model that had twin 12ft propellers with 6 blades each! Interestingly enough these blades could be adjusted to produce maximum thrust under certain conditions, an early recognition of the need for changing blade pitch. Without a doubt, the most expensive and spectacular project of its time was that carried out by Sir Hiram Maxim. His numerous experiments with propellers, culminated in the construction of a huge, four-ton biplane in 1890. This contraption was powered by two 180hp steam engines that each drove propellers 17ft, 10inches in diameter and weighing 135lbs. The two-blade propellers, inversely tapered and squared at the tips 5 ? ft wide, were made of American Pine, planed smooth, covered with glued canvas and stayed to the propeller shafts with steel wire to handle the high thrust loads. These massive propellers produced 1,100lbs of thrust each during full power while rotating at 425rpm. Maxim's jumbo creation didn't last long however, it jumped the test track and suffered extensive damage. Hands down, the most influential aviation pioneers were the Wright brothers. They had concluded that a propeller was simply a whirling wing, but didn't have the appropriate information to consult when comprehending the fundamental principles of blade shape and motion. This dilemma made designing the propeller one of the Wright brothers most challenging problems. Despite the lack of previous information to consult, the brothers were able to learn, through investigation and trial/error, that large propeller diameters would produce high thrust for a given power input. The brothers also determined that high torque produced by large, slow turning blades adversely affected the flying qualities (p-factor). On their first aircraft, they utilized 8 ? ft propellers installed behind the wind to minimize airflow disturbance, incorporated counter-rotating propellers to eliminate the problems associated with torque, and gained thrust efficiency by reducing the blades' rotational speed using a chain and sprocket transmission. The Wright brother's propeller was 66% efficient which was much higher that any other propeller of the

Oldowan Tradition - Humankinds First Stone Tools

Oldowan Tradition - Humankinds First Stone Tools The Oldowan Tradition (also called Oldowan Industrial Tradition or Mode 1 as described by Grahame Clarke) is the name given to a pattern of stone-tool making by our hominid ancestors, developed in Africa by about 2.6 million years ago (mya) by our hominin ancestor Homo habilis (probably), and used there until 1.5 mya (mya). First defined by Louis and Mary Leakey at Olduvai Gorge in the Great Rift Valley of Africa, the Oldowan tradition is to date the earliest manifestation of stone tool making on our planet. Further, it is global in scope, a toolkit thought to have been carried out of Africa by our hominin ancestors as they left to colonize the rest of the world. To date, the oldest known Oldowan tools were found at Gona (Ethiopia) at 2.6 ma; the latest in Africa is 1.5 mya at Konso and Kokiselei 5. The end of the Oldowan is defined as the appearance of Mode 2 tools or Acheulean handaxes. The earliest Oldowan sites in Eurasia are 2.0 mya at Renzidong (Anhui Province China), Longgupo (Sichuan Province) and Riwat (on the Potwar Plateau in Pakistan), and the latest so far is at Isampur, 1 mya in the Hungsi valley of India. Some discussion of the stone tools found at Liang Bua Cave in Indonesia suggests that they are Oldowan; which either lends support to the notion that the Flores hominin is a devolved Homo erectus or that the Oldowan tools were not specific to species. What Is an Oldowan Assemblage? The Leakeys described the stone tools at Olduvai as cores in the shapes of polyhedrons, discoids, and spheroids; as heavy and light duty scrapers (sometimes called nuclà ©us racloirs or rostro carà ©nà ©s in the scientific literature); and as choppers and retouched flakes. Selection for raw material sources  can be seen in Oldowan by about 2 mya, at sites like Lokalalei and Melka Kunture in Africa and Gran Dolina in Spain. Some of that is surely related to characteristics of the stone and what the hominid planned to use it for: if you have a choice between basalt and obsidian, youd select basalt as a percussion tool, but obsidian to break down into sharp-edged flakes. Why Did They Make Tools at All? The purpose of the tools is somewhat in controversy. Some scholars are inclined to think that most of the tools are simply steps in manufacturing sharp-edged flakes for cutting. The stone-tool making process  is known as chaà ®ne opà ©ratoire in archaeological circles. Others are less convinced. There is no evidence that our hominid ancestors were eating meat before about 2 mya, so these scholars suggest that the stone tools must have been for use with plants, and the percussion tools and scrapers may have been tools for plant processing. Admittedly, however, its hard to make assumptions on negative evidence: the oldest Homo remains we have only date to 2.33 mya in the Nachukui Formation of West Turkana in Kenya, and we dont know if there are earlier fossils we havent found yet that will be associated with Oldowan, and it may be that Oldowan tools were invented and used by another non-Homo species. History The Leakeys  work in Olduvai Gorge in the 1970s was quite revolutionary by any standards. They defined the original chronology of the Oldowan assemblage in the Great Rift Valley of eastern Africa including the following periods; the stratigraphy within the region; and the material culture, the characteristics of the stone tools themselves. The Leakeys also focused on geological studies of the paleo-landscape of the Olduvai Gorge and its changes over time. In the 1980s, Glynn Isaac and his team worked at the more-or-less contemporaneous deposits at Koobi Fora, where they used experimental archaeology, ethnographic analogy, and primatology to explain the Oldowan archaeological record. They developed testable hypotheses about ecological and economic conditions that might have triggered stone tool making- hunting, food sharing, and occupying a home base, all of which is also done by primates, with the exception of the production of sharp-edged tools. Recent Investigations Recent expansions to the interpretations built by the Leakeys and Isaac have involved adjustments to the time span of use: discoveries at sites such as Gona have pushed the date of the first tools a half-million years earlier from what the Leakeys found at Olduvai. Also, scholars have recognized a considerable variability within the assemblages; and the extent of the Oldowan tool use throughout the globe has become recognized. Some scholars have looked at the variation in stone tools and argued that there must have been a Mode 0, that Oldowan is the result of a gradual evolution from a common tool-making ancestor of both humans and chimps, and that phase is missing in the archaeological record. That has some merit, because Mode 0 tools may have been made of bone or wood. Not everyone agrees with this, and, currently, it seems that the 2.6 mya assemblage at Gona still represents the earliest stages of lithic production.
