Character may almost be called the most effective means of persuasion.

People do not seem to realize that their opinion of the world is also a confession of character.

It wasn't until late in life that I discovered how easy it is to say "I don't know."

Oh, I offended you with my opinion? You should hear the the ones I keep to myself.

Lie to a liar, for lies are his coin; steal from a thief, for that is easy; lay a trap for a trickster and catch him at first attempt, but beware of an honest man.

No amount of evidence will ever persuade an idiot.

My experience has shown me that we win justice quickest by rendering justice to the other party.

Tact is the knack of making a point without making an enemy.

Think twice before you speak, because your words and influence will plant the seed of either success or failure in the mind of another.

The most important single ingredient in the formula of success is knowing how to get along with people.

It's frightful that people who are so ignorant should have so much influence.

But all my life through, the very insistence on truth has taught me to appreciate the beauty of compromise.
