At the risk of repeating what many have said, 1) take an inventory at what your are naturally good at - what gives you the greatest pleasure in life - what interests you; what can you do with little effort that is harder for others? And 2) decide that you will find what you want to do. Look for clues that will confirm what feels right. Problem we all face is that we often don't know what direction to take because we think about it so much. If you trust yourself, the direction will become evident if you let go. In the interim, use your time productively by going on to college or technical school. This will stimulate growth and help give you more experiences to guide you.
