Be fit for more than the thing you are now doing. Let everyone know that you have a reserve in yourself, — that you have more power than you are now using. If you are not too large for the place you occupy, you are too small for it.

James A. Garfield (1831-1881) US President (1881), lawyer, lay preacher, educator

“Elements of Success,” speech at Spencerian Business College, Washington, DC (29 Jun 1869)
