I do not think much of a man who is not wiser today than he was yesterday.

I am not bound to win, but I am bound to be true. I am not bound to succeed, but I am bound to live up to what light I have.

Every person’s happiness is their own responsibility.

You cannot escape the responsibility of tomorrow by evading it today.

When you reach the end of your rope, tie a knot and hang on.

All I have learned, I learned from books.

Give me six hours to chop down a tree and I will spend the first four sharpening the axe.

The best thing about the future is that it comes one day at a time.

The better part of one’s life consists of his friendships.

I am not concerned that you have fallen — I am concerned that you arise.

I don’t know who my grandfather was; I am much more concerned to know what his grandson will be.

You can have anything you want if you want it badly enough. You can be anything you want to be, do anything you set out to accomplish if you hold to that desire with singleness of purpose.

My great concern is not whether you have failed, but whether you are content with your failure.

Life is hard but so very beautiful

Be sure you put your feet in the right place, then stand firm.

Human action can be modified to some extent, but human nature cannot be changed.

The best way to predict your future is to create it

I distrust the wisdom if not the sincerity of friends who would hold my hands while my enemies stab me.

If we have no friends, we have no pleasure; and if we have them, we are sure to lose them, and be doubly pained by the loss.
