A man who is 'of sound mind' is one who keeps the inner madman under lock and key.

All things seek for comfort and no one wants discomfort. A sound mind does not just improve speed; it increases efficiency and joy, and bond the body and the soul perfectly as well!

A great man is one who leaves others at a loss after he is gone.

It doesn't sound like you have an incubator.

Laughter is the mind's intonation. There are ways of laughing which have the sound of counterfeit coins.

Surely the only sound foundation for a civilization is a sound state of mind.
