Know or listen to those who know.

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

If you're going through hell, keep going.

Leap, and the net will appear.

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

The secret of getting ahead is getting started.

What you do today can improve all your tomorrows.

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

To know oneself, one should assert oneself.
