- Johnny Lawrence: Never "can't". Those are just words, they're meaningless. It's time for you to get out of that bed and do something. You're not a kid anymore, the world isn't going to just hand it to you. You want something, you're going to have to crawl across the floor. Use your damned teeth if you have to. You're going to do whatever it takes. And I'm always going to be right here next to you... because I'll always be your teacher.
- Kumiko: [Reading an old letter from Mr Miyagi] In life, we'll always lose our way. But it is people, not the signs, that guide us back to the right path.
- John Kreese: If your mind is agile, so are you. That's the best way to beat your enemy. Not just with brute strength, but you have to fight smart. Do that, and you'll always come out on top.
