To be a good loser is to learn how to win.
Go for it now. The future is promised to no one.
Begin to be now what you will be hereafter.
Be kind whenever possible. It is always possible.
Quality is not an act, it is a habit.
Well done is better than well said.
Do not weep do not wax indignant. Understand.
Things do not happen. Things are made to happen.
If you've got a talent, protect it.
Know or listen to those who know.
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.
