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

It's always too early to quit.

To know oneself, one should assert oneself.

Quality is not an act, it is a habit.

Leap, and the net will appear.

The secret of getting ahead is getting started.

What you do today can improve all your tomorrows.

Either you run the day or the day runs you.

Be gentle to all and stern with yourself.
