It's always too early to quit.

To be a good loser is to learn how to win.

The dog that trots about finds a bone.

To know oneself, one should assert oneself.

Well done is better than well said.

Always desire to learn something useful.

Go for it now. The future is promised to no one.

Problems are not stop signs, they are guidelines.

Do not weep do not wax indignant. Understand.
