"A man is not to be credited for what he does by constraint and necessity."

"The greater you esteem yourself, the less you will be esteemed by others."

"I have always thought it a very foolish question to ask a man, what he would not do for a considerable sum of money."

"Perseverance is the key to success."

"Don't give up on what you believe in."

"I've been through worse."

"You learn to live with the pain."
