When to give up?

something to ponder...
"It is up to us as single individuals to oppose the forces of our lives. I have said this to you countless times: Only a warrior can survive. A warrior knows that he is waiting and what he is waiting for: and while he waits he wants nothing and thus whatever little thing he gets is more than he can take. If he needs to eat he finds a way, because he is not hungry; if something hurts his body he finds a way to stop it, because he is not in pain. To be hungry or to be in pain means that a man is no longer a warrior; and the forces of his hunger and pain will destroy him." -Juan Matus
