> ...once you stop setting yourself impossible goals, lead a simple life, find humility, have a minimum amount of discipline, you won't be so unhappy.

As George Bernard Shaw said, "The reasonable man adapts himself to the world: the unreasonable one persists in trying to adapt the world to himself. Therefore all progress depends on the unreasonable man."

I accept my unhappiness as the price of striving to be the best I can be, however little that might amount to. Anything less is a waste of my one and only chance (i.e. an all too brief existence) to make a difference in this world.
