Lao Tzu wrote in the Tao Te Ching, "He who knows when he has enough shall always have enough." It's not a particularly cryptic expression and it means precisely what it sounds like. So why am I writing this?
For starters, lets look at what it really means to want something. If you were to look at your life just as it is and name something that is missing, what would occur? If you are like most people you would begin to evaluate the joy it might bring, maybe compare it to the joy you feel now, maybe express the preference a bit stronger.
