When confronted with two courses of action I jot down on a piece of paper all the arguments in favor of each one, then on the opposite side I write the arguments against each one. Then by weighing the arguments pro and con and cancelling them out, one against the other, I take the course indicated by what remains.

Mankind are dastardly when they meet with opposition.

Never contradict anybody.

He that displays too often his wife and his wallet is in danger of having both of them borrowed.

Diligence overcomes difficulties; sloth makes them.

To be thrown upon one's own resources, is to be cast in the very lap of fortune.
