It's always too early to quit.

Be gentle to all and stern with yourself.

Do not weep do not wax indignant. Understand.

If you think you can do it, you can.

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

The most effective way to do it, is to do it.

The dog that trots about finds a bone.

After a storm comes a calm.

To know oneself, one should assert oneself.
