Be more concerned with your character than with your reputation, for your character is what you are, while your reputation is merely what others think you are.
Be wiser than other people if you can; but do not tell them so.
Develop success from failures. Discouragement and failure are two of the surest stepping stones to success.
Don't be afraid of enemies who attack you. Be afraid of the friends who flatter you.
Fear doesn't exist anywhere except in the mind.
Fear not those who argue but those who dodge.
Feeling sorry for yourself and your present condition is not only a waste of energy but the worst habit you could possibly have.

Talk to someone about themselves and they'll listen for hours.
The essence of all art is to take pleasure in giving pleasure.
The ideas I stand for are not mine. I borrowed them from Socrates. I swiped them from Chesterfield. I stole them from Jesus. And I put them in a book. If you don't like their rules, whose would you use?
Those convinced against their will are of the same opinion still.
Unjust criticism is often a disguised compliment. It often means that you have aroused jealousy and envy. Remember that no one ever kicks a dead dog.
When dealing with people, let us remember we are not dealing with creatures of logic. We are dealing with creatures of emotion, creatures bristling with prejudices and motivated by pride and vanity.
When we hate our enemies, we are giving them power over us: power over our sleep, our appetites, our blood pressure, our health, and our happiness.
You can make more friends in two months by becoming interested in other people than you can in two years by trying to get other people interested in you.
