Everything Sonny learned was from Joe Scully.
"Trust no one.” (Scully’s first rule.)
“When it’s you and your enemy, only one of you walks away.” (Scully’s most important rule.)
“Too much contentment can make you soft.”
“Sometimes you can get your head so high in the clouds, you forget to keep your feet on the ground.”
“Don’t promise anything until you know you can deliver.”
“When you’re the boss, keep your hands clean.”
“If you get too full of yourself, bend down and pick up a penny of the street."
