Learn perspectives on life, sets of values etc. of different people. See what sounds appealing to you and try implementing that. If, over time, you have problems with motivating yourself to follow that path or it somehow feels wrong otherwise, try analyzing what exactly is the nature of the problem and correct for that, or choose a different path entirely. Using this method, over time, you will discover your natural preferences and will be able to construct a life that agrees with you and feels right.
