Don't quit when the tide is the lowest,
for it's just about to turn.
Don't quit over doubts and questions.
for there's something you may learn.
Don't quit when the night is the darkest,
for it's just a while till dawn,
Don't quit, when you've run the farthest,
for the race is almost won.
Don't quit, when the hill is the steepest,
For your goal is almost nigh,
Don't Quit, for you're not a failure,
Until you fail to try.
(wigdon from the "Q")
