I think you are wrong to want a heart. It makes most people unhappy. If you only knew it, you are in luck not to have a heart.

Pay no attention to the man behind the curtain!

Familiarity with any great thing removes our awe of it. The great general is only terrible to the enemy; the great poet is frequently scolded by his wife; the children of the great statesman clamber about his knees with perfect trust and impunity; the great actor who is called before the curtain by admiring audiences is often waylaid at the stage door by his creditors.

Hearts will never be practical until they can be made unbreakable.

If you only have brains on your head you would be as good a man as any of them, and a better man than some of them. Brains are the only things worth having in this world, no matter whether one is a crow or a man.

To 'know Thyself' is considered quite an accomplishment.

I'll miss you most of all scarecrow.
