Some of the people here have misunderstood my point, it is welcome anyway other kind of quotes but what I really meant was philosophic quotes like Vito Corleone`s, those which you would learn about the life or they could be useful, like the one of Carlo Gambino in the first post. Here is one of Joseph Bonanno

"Frienship,connections,family ties,trust,loyalty,obedience-this was the glue that held us together."-Joe Bonanno
