Success is stumbling from failure to failure with no loss of enthusiasm.

A joke is a very serious thing.

I am always ready to learn although I do not always like being taught.

If you cannot read all your books, at any rate handle, or as it were, fondle them – peer into them, let them fall open where they will, read from the first sentence that arrests the eye, set them back on the shelves with your own hands, arrange them on your own plan so that if you do not know what is in them, you at least know where they are. Let them be your friends; let them at any rate be your acquaintances. If they cannot enter the circle of your life, do not deny them at least a nod of recognition.

If you cannot read all your books...fondle them---peer into them, let them fall open where they will, read from the first sentence that arrests the eye, set them back on the shelves with your own hands, arrange them on your own plan so that you at least know where they are. Let them be your friends; let them, at any rate, be your acquaintances.
