The man who affects to display his learning, will be frequently questioned; and if found superficial, will be ridiculed and despised; if otherwise, he will be deemed a pedant. Nothing can lessen real merit (which will always shew itself) in the opinion of the world, but an ostentatious display by its possessor.

Take care in your minutes, and the hours will take care of themselves.
