The deepest sin against the human mind is to believe things without evidence. — Thomas H. Huxley. English biologist and comparative anatomist (1825–1895)
Perhaps the most valuable result of all education is the ability to make yourself do the thing you have to do, when it ought to be done, whether you like it or not; it is the first lesson that ought to be learned; and however early a man's training begins, it is probably the last lesson that he learns thoroughly.
Make up your mind to act decidedly and take the consequences. No good is ever done in this world by hesitation.
