"The best things in life are nearest: Breath in your nostrils, light in your eyes, flowers at your feet, duties at your hand, the path of right just before you. Then do not grasp at the stars, but do life's plain, common work as it comes, certain that daily duties and daily bread are the sweetest things in life." ~Robert Louis Stevenson
As the quote above eloquently states, the things that make us truly happy are very simple. For me being close to nature and my loved ones without the anxiety and constant distractions of technology is when I am most content. So why then is the majority of mankind pursuing material wealth and the stuff that it buys. The endless process of buying, using, storing and paying for stuff can give people the illusion of purpose or success, but it will never bring true joy and contentment.
Some of the most unhappy people in the world are those that have achieved this materialistic definition of success (1 Tim 6:9,10). I believe this is because having achieved their goals they can no longer hope that if they just get [X] they will finally be happy. Those that have not yet grabbed a hold of the brass ring don't realize its just a round piece of metal and at the same time they can still find purpose in working to attain it.
