- Jack Slack: We are born alone. And we die alone.
- Jem Belcher: But you're not alone. I'm here.
- Jack Slack: Every man is alone, Jem.
- Bill Warr: You can't rely on natural ability alone. Boxing's an art. It's a craft. Boxers like, um... like writers, they stand alone.
- Jack Slack: Cryin' , it's ain't gonna help. In life, don't no one give two shits about you. The only way to protect yourself is to attack. To fight.
- Walter: Self-hatred is staring back at you. Discipline yourself in the trivialities of life first, then all matters greater than this will follow. And only God determines the weal and woe of this world, but man controls his own mind, readying yourself for any such tempest of fate that may blow your way. The only blame that should weigh upon your shoulders, young man, is that of self-neglect. Now, you must embrace the sovereignty of your own mind.
- Lord Rushworth: You know what I love about fighting?
- Jem Belcher: What's that?
- Lord Rushworth: It's the only sport where money is made by men doing somethin' they'd ordinarily be locked up for.
- Jack Slack: Gotta know who you are in life. Money comes and goes as does women. It's you who decides what kind of man you're gonna be. When your grave's filled and your flesh rots away all you leave behind is your name.
