To know oneself, one should assert oneself.

If you're going through hell, keep going.

Well done is better than well said.

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

If you think you can do it, you can.

Quality is not an act, it is a habit.

Be thine own palace, or the world's thy jail.

The dog that trots about finds a bone.

I can, therefore I am.
