Be gentle to all and stern with yourself.
If you're going through hell, keep going.
To be a good loser is to learn how to win.
Know or listen to those who know.
Leap, and the net will appear.
Quality is not an act, it is a habit.
Be kind whenever possible. It is always possible.
It's always too early to quit.
Who seeks shall find.
Either you run the day or the day runs you.
As man sows, so shall he reap. In works of fiction, such men are sometimes converted. More often, in real life, they do not change their natures until they are converted into dust.
There's time enough, but none to spare.
