In Western societies, particularly the United States, people are led to believe that material wealth defines success. Sitting on a mountain, contemplating life, is not seen by the vast majority of Americans as a sign of success. Unless...you've earned enough money to do so! Hard work and/or innovative work that is rewarded by a substantial amount of money is recognized as the hallmark of a successful life.
When I think about contentment, for some reason fancy cars and big houses never enters my mind. I see a person sitting by a stream, the ocean, on a mountain or hillside, or...just relaxing in his or her back yard while looking and listening to the birds or smiling at their children and/or their significant other. Can that really be contentment? Can that actually be deemed success? Hmm...think about it. What do most people look forward to? Being able to retire and "enjoy" life...right?! Well, if you watch your resources, don't go crazy spending needlessly, ignore the cravings to mindlessly follow marketers, work at a job that brings you satisfaction, perhaps affords you a flexible schedule, you can "retire" relatively early - or at least semi-retire. All it takes is the ability to be content with a different kind of "Western" success. That's it.
There's far too much stress created by trying to strive for the portrayal of success as opposed to what might really BE success. Step back and take inventory of your life. You may have already achieved success and may not even realize it!
