Books are to be distinguished by the grandeur of their topics even more than by the manner in which they are treated.

Do what you love. Know your own bone; gnaw at it, bury it, unearth it, and gnaw it still.

Do not worry if you have built your castles in the air. They are where they should be. Now put the foundations under them.

Do not trouble yourself much to get new things, whether clothes or friends... Sell your clothes and keep your thoughts.

Do not be too moral. You may cheat yourself out of much life so. Aim above morality. Be not simply good; be good for something.

Disobedience is the true foundation of liberty. The obedient must be slaves.

Dreams are the touchstones of our character.

Books can only reveal us to ourselves, and as often as they do us this service we lay them aside.

Do not hire a man who does your work for money, but him who does it for love of it.

Books are the treasured wealth of the world and the fit inheritance of generations and nations.

Beware of all enterprises that require a new set of clothes.

Being is the great explainer.

Before printing was discovered, a century was equal to a thousand years.

Be true to your work, your word, and your friend.

Could a greater miracle take place than for us to look through each other's eyes for an instant?
