“Tom, don't let anybody kid you. It's all personal, every bit of business. Every piece of shit every man has to eat every day of his life is personal. They call it business. OK. But it's personal as hell. You know where I learned that from? The Don. My old man. The Godfather. If a bolt of lightning hit a friend of his the old man would take it personal. He took my going into the Marines personal. That's what makes him great. The Great Don. He takes everything personal Like God. He knows every feather that falls from the tail of a sparrow or however the hell it goes? Right? And you know something? Accidents don't happen to people who take accidents as a personal insult.”

“Never show anger at slight, tell nothing. Earn respect from everyone by deeds, not Words. Respect the members of your Blood Family. Gambling was Recreation, not a way to earn a Living. Love your Father, your Mother, your Sister but beware of Loving any other Woman than your Wife. And a Wife was a woman who bore your Children. And once that happened to You, your Life was Forfeit to give them their daily bread”

“What is past is past. never go back. Not for excuses. Not for justification, not for happiness. You are what you are, the world is what it is.”
