Wasting life, wasting time, putting off important goals. Not a straightforward problem. The goals of our daydreams often revolve around fame or fortune, standing out from the crowd. If we all buy into that culture then most of the crowd will judge themselves to have an empty life. Sometimes a life event or even just age will lead a person to reconsider "what really matters." I think you can help that process along by questioning your own priorities and talking about your goals with people close to you. An unexamined goal may not be worth pursuing.
