The wise does at once what the fool does at last.
Things do not happen. Things are made to happen.
Only the educated are free.
It's always too early to quit.
If you can dream it, you can do it.
I can, therefore I am.
If you think you can do it, you can.
Leap, and the net will appear.
To be a good loser is to learn how to win.
The dog that trots about finds a bone.
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.
