What do you do when there's nowhere to turn? You drive straight ahead.

Great difficulties may be surmounted by patience and perseverance.

However vast the darkness, we must supply our own light.

Aim above morality. Be not simply good; be good for something.

When you run into something interesting, drop everything else and study it.

Happiness is a simple, frugal heart.

Nobody has ever measured, not even poets, how much the heart can hold.

Patience is a necessary ingredient of genius.

Be happy, take care of your teeth, always let your conscience be your guide.

Do not fear to be eccentric in opinion, for every opinion now accepted was once eccentric.

The greater the difficulty, the more the glory in surmounting it.

Someone's sitting in the shade today because someone planted a tree a long time ago.
