Know or listen to those who know.

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

Quality is not an act, it is a habit.

If you've got a talent, protect it.

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

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

Well done is better than well said.

If you're going through hell, keep going.

To know oneself, one should assert oneself.
