To know oneself, one should assert oneself.

The dog that trots about finds a bone.

Well done is better than well said.

It's always too early to quit.

Be kind whenever possible. It is always possible.

If you've got a talent, protect it.

Do not weep do not wax indignant. Understand.

The secret of getting ahead is getting started.

If you're going through hell, keep going.
