It's always too early to quit.
Be gentle to all and stern with yourself.
To be a good loser is to learn how to win.
If you've got a talent, protect it.
Quality is not an act, it is a habit.
If you think you can do it, you can.
Do not weep do not wax indignant. Understand.
Things do not happen. Things are made to happen.
The wise does at once what the fool does at last.
Never complain and never explain.
Everyone who's ever taken a shower has an idea. It's the person who gets out of the shower, dries off and does something about it who makes a difference.
