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

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

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.

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.

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.

This is the mark of a really admirable man: steadfastness in the face of trouble.

We can do anything we want to if we stick to it long enough.

Continuous effort — not strength or intelligence — is the key to unlocking our potential.

Abandon the idea that you are ever going to finish. Lose track of the 400 pages and write just one page for each day; it helps. Then, when it gets finished, you are always surprised.

It isn’t enough to talk about peace. One must believe in it. And it isn’t enough to believe in it. One must work at it.

Half-finished work generally proves to be labor lost.

Don't waste life in doubts and fears; spend yourself on the work before you, well assured that the right performance of this hour's duties will be the best preparation for the hours and ages that will follow it.

There will be obstacles. There will be doubters. There will be mistakes. But with hard work, there are no limits.

The things are mighty few on earth That wishes can attain. Whate'er we want of any worth We've go to work to gain.
