To know oneself, one should assert oneself.

The dog that trots about finds a bone.

Well done is better than well said.

If you're going through hell, keep going.

Do not weep do not wax indignant. Understand.

Never complain and never explain.

I can, therefore I am.

What you do today can improve all your tomorrows.

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