The problem with “discovering your purpose” is that the statement presupposes the existence of purpose. Rather than wandering aimlessly through life (or even worse, grasping on to some sort of false promise of meaning), take some initiative and create meaning for yourself, on your own terms. Searching blindly for purpose is like trying to solve a puzzle with no possible solution and leads only to frustration. Accepting the purpose that religion or other institutions prescribe leads to a lifetime of guilt and codependency. Rather than feeling like you are by nature a failure who must grovel at the knees of God or endlessly searching for another purpose, accept who you are and come to terms with yourself and your own passions. Have some confidence in your ability to choose right from wrong and live a worthwhile life according to your own standards.
