To be a good loser is to learn how to win.
The secret of getting ahead is getting started.
Who seeks shall find.
It's always too early to quit.
Wherever you are - be all there.
The dog that trots about finds a bone.
If you're going through hell, keep going.
If you can dream it, you can do it.
If you've got a talent, protect it.
Problems are not stop signs, they are guidelines.
The answer to old age is to keep one's mind busy and to go on with one's life as if it were interminable. I always admired Chekhov for building a new house when he was dying of tuberculosis.
