There's a concept I use, called the Golden Thread, if you look back over the decisions you made, even as a child, did you come to play outside or did you stay inside and read a book, really basic stuff. If you join all the things that you chose to do, you do see a golden thread weaving through your life, once you find that, it's much easier to make a decision on what my purpose is or what my aim could be. If it changes, there's not that same sense of failure as if you haven't reached a goal.
