Don't be afraid to give up the good to go for the great.
Our ambition should be to rule ourselves, the true kingdom for each one of us; and true progress is to know more, and be more, and to do more.
Sir John Lubbock
Every man is said to have his peculiar ambition.
Ambition can creep as well as soar.
When ambition ends, happiness begins.
Keep away from small people who try to belittle your ambitions. Small people always do that, but the really great make you feel that you, too, can become great.
It is the constant fault and inseparable evil quality of ambition, that it never looks behind it.
He that fails in his endeavors after wealth or power will not long retain either honesty or courage.
The passion of self-aggrandizement is persistent but plastic; it will never disappear from a vigorous mind, but may become morally higher by attaching itself to a larger conception of what constitutes the self.
Charles Horton Cooly
Very few people are ambitious in the sense of having a specific image of what they want to achieve. Most people's sights are only toward the next run, the next increment of money.
Judith M. Bardwick
A person who aims at nothing is sure to hit it.
