I go at what I have to do as if there were nothing else in the world for me to do.

No man fails who does his best ...

Always do more than is required of you.

You must not only aim aright, But draw the bow with all your might.

An honest try is better than success.

The truth is I'm doing the best I can with the world as I see it.

You must make the most strenuous efforts. Throughout this life, you can never be certain of living long enough to take another breath.

No individual or people can achieve anything without industry suffering, and sacrifice.

When do any of us ever do enough?
