It's always too early to quit.
Problems are not stop signs, they are guidelines.
Be gentle to all and stern with yourself.
If you can dream it, you can do it.
The dog that trots about finds a bone.
To be a good loser is to learn how to win.
To know oneself, one should assert oneself.
Who seeks shall find.
The wise does at once what the fool does at last.
Leap, and the net will appear.
We have, I fear, confused power with greatness.
