Often in the casual remarks of great men one learns their true mind in an intimate way.

A man can wear out a particular part of his mind by continually using and tiring it, just in the same way he can wear out the elbows of his coat.

The sky is not the limit. Your mind is.

Strong minds discuss ideas, average minds discuss events, weak minds discuss people.

Whoever controls the media, controls the mind.

I would rather be stricken blind than to live without expression of mind.
