I see nothing wrong with the human trait to desire. In fact, I consider it integral to our success mechanism. Becoming attached to what we desire is what causes the trouble. If you must have it in order to be happy, then you are denying the happiness of the here and now.
While goals are chosen, a purpose is discovered. Our purpose is something we have been doing all along, and will continue to do, regardless of circumstances, until the day we die.
