A Quote by Jeremiah W. Jenks on action, community, danger, ideas, individuality, learning, mind, purpose, and work

The inlet of a man's mind is what he learns; the outlet is what he accomplishes. If his mind is not fed by a continued supply of new ideas which he puts to work with purpose, and if there is no outlet in action, his mind becomes stagnant. Such a mind is a danger to the individual who owns it and is useless to the community.
