Ambition is the last refuge of the failure.

It is stasis that kills you off in the end, not ambition.

To be happy at home is the ultimate result of all ambition, the end to which every enterprise and labor tends, and of which every desire prompts prosecution.

If we all can persevere, if we can in every land and office look beyond our own shores and ambitions, then surely the age will dawn in which the strong are just and the weak secure and the peace preserved.

Nothing leads so straight to futility as literary ambitions without systematic knowledge.

Our ambition should be to rule ourselves, the true kingdom for each of us; and true progress is to know more, and be more, and to do more.

Now what should happen when you make a mistake is this: You take your knocks, you learn your lessons and then you move on. That’s the healthiest way to deal with a problem.

There is no failure except in no longer trying.

Remember your dreams and fight for them. You must know what you want from life. There is just one thing that makes your dream become impossible: the fear of failure.
