My dear,

The great do things which you feel no one else can do. But the really great do something much more important than that.

The really great make you feel that you, too, can become great.

The great are content with only themselves being great. But the really great aim to make everyone as great, or even greater, than they are.

We need less great and more really great.

Falsely yours,
Samuel Langhorne Clemens
