Know or listen to those who know.

The secret of getting ahead is getting started.

Well done is better than well said.

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

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

Be gentle to all and stern with yourself.

It's always too early to quit.

What you do today can improve all your tomorrows.

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