The human body has an enormous capacity for adjusting to trying circumstances. I have found that one can bear the unbearable if one can keep one's spirit strong, even when one's body is being tested. Strong convictions are the secret of surviving deprivation. Your spirit can be full even when your stomach is empty.

Now we are the masters of our fate, that the task which has been set us is not above our strength; that its pangs and toils are not beyond our endurance. As long as we have faith in our cause and an unconquerable willpower, salvation will not be denied us.

One must never be discouraged by defeats in one's youth, but continue to learn throughout one's whole life.

We must go on and on like the gun-horses, till we drop.

If you can't fly, run; if you can't run, walk; if you can't walk, crawl; but by all means keep moving.

Keep moving, for it may well be that the greatest song has not yet been sung, the greatest book has not been written, the highest mountain has not been climbed.
