Be gentle to all and stern with yourself.

If you're going through hell, keep going.

Quality is not an act, it is a habit.

If you think you can do it, you can.

Do not weep do not wax indignant. Understand.

Either you run the day or the day runs you.

You never know what motivates you.

The secret of getting ahead is getting started.

It's always too early to quit.
