Well done is better than well said.

Be gentle to all and stern with yourself.

Know or listen to those who know.

It's always too early to quit.

Do not weep do not wax indignant. Understand.

If you think you can do it, you can.

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

Things do not happen. Things are made to happen.

The secret of getting ahead is getting started.
