I am one of those cases which perhaps are not all that rare today: I had a task, did not do it, and now the failure is wrecking my life. I ought to have done something positive with my life, to have become a star in the sky. Instead of which I remained stuck on earth, and now I am gradually fading out. My life has really become meaningless and so it consists only of futile episodes.

Wittgenstein, in a letter to Engelmann
