Obstacles don't have to stop you. If you run into a wall, don't turn around and give up. Figure out how to climb it, go through it, or work around it.

Winners never quit and quitters never win.

We run, not only because we think it is doing us good, but … because it helps us to do other things better.

Believe me; the reward is not so great without the struggle.

I did the best I could with what I had.

Walk a single path, becoming neither cocky with victory nor broken with defeat, without forgetting caution when all is quiet or becoming frightened when danger threatens.
