To know oneself, one should assert oneself.

The dog that trots about finds a bone.

If you think you can do it, you can.

Well done is better than well said.

Know or listen to those who know.

Do not weep do not wax indignant. Understand.

The wise does at once what the fool does at last.

What you do today can improve all your tomorrows.

Expect problems and eat them for breakfast.
