He who puts off nothing till tomorrow has done a great deal.
Always leave something to wish for; otherwise you will be miserable from your very happiness.
Attain and maintain a reputation, for it is the usufruct of fame. A stiff climb, for it is the issue of excellence, as rare as mediocrity is common.
Wisdom and courage make mutual contributions to greatness.
Dreams will get you nowhere, a good kick in the pants will take you a long way.
He that has satisfied his thirst turns his back on the well.
