Don't quit when the tide is the lowest,
For it's just about to turn;
Don't quit over doubts abd questions,
For there's something you may learn.
Don't quit when the night is darkest,
For it's just a while till dawn;
Don't quit when you've ran the farthest,
For the race is almost won,
Don't quit when the hill is steepest,
For your goal is almost near;
Don't quit, for you're not a failure
Until you fail to try

i guess now is the time to try.
