Know or listen to those who know.
Well done is better than well said.
If you think you can do it, you can.
What you do today can improve all your tomorrows.
If you've got a talent, protect it.
Begin to be now what you will be hereafter.
Be gentle to all and stern with yourself.
The secret of getting ahead is getting started.
To be a good loser is to learn how to win.
Who seeks shall find.
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.
