The tragedy is that so many have ambition and so few have ability

A man must not deny his manifest abilities, for that is to evade his obligations.

Almost any idea is good if a man has ability and is willing to work hard.

An idea isn't worth much until a man is found who has the energy and ability to make it work.

Don't let ambition get so far ahead that it loses sight of the job at hand

If a person holds no ambitions in this world, he suffers unknowingly. If a person holds ambitions, he suffers knowingly, but very slowly.
