What to do with ones life?

Knowing that one day I am going to die does make life more valuable, even precious. But the question is, what am I to do with this precious cargo? Its already running out, this fuel of living and its been depleting since my birth. The burden of figuring out the answer is too big a responsibility. No one knows the answer, no one. Everyone has a vague opinion, but that doesn't help. Your answer is not my solution. It doesn't fit me. It may have something that would provide food for thinking, but that's all it is. Heidegger, Kierkegaard, Sartre, no one helps! They only make you more aware of the problem, makes you aware that the rabbit hole goes much deeper!
