Tell your brain to tell your legs to get their asses moving.

Amanda: Look, Sam, I don't know what's going on with you.
Sam: No. You don't.  And if you really think that Karate is the problem, then you haven't been paying attention.

Robby: You're wasting your time, old man. The last thing I need right now is another sensei.
Kreese: Fair enough. I don't think there's much I can teach you right now anyway. Except maybe this. All that Miyagi do mumbo jumbo, that might score you points in a tournament, but now, you're in the real world, kid. You might want to learn to strike first.

Hey, Danny boy. Nice try, but you can't win a war with diplomacy. So I suggest you prepare your students for battle because now it's open season on them and you. 

Kreese

Tory: I know I should've come to see you, I just didn't know how to help.
Miguel: So you did nothing.
Tory: I felt guilty about everything, but we're doing everything we can to get back at Miyagi do for what they did to you. It's like what Sensei Kreese says, if one of us gets hurt, we all got hurt.
Miguel: Nobody else got hurt, Tory. I'm the one in a wheelchair.
Tory: Yeah, I just meant- 
Miguel: I know what you meant. I never cared about Miyagi Do or Kreese. I cared about us. 
Tory: Did you? Or were you just going out with me to get Sam's attention?

Hawk: What do you want?
Sam: Payback.

Miguel: You're the one who is giving up. You let Kreese take your dojo. You let Hawk, Tory, and everyone else think you're weak.
Johnny: Because it was a mistake, to begin with. I should have never bought back Cobra Kai. Look what happened!
Miguel: What happened is you helped a bunch of people then walked away like a pussy. You're a sensei. It's who you are. If you can't see that you're blind.

Captain: You got a death wish kid? 
Young Kreese: Not wishing for it, just not afraid of it. Some people can't tell the difference. 

Kreese: You're a feisty one, but I like that. I like it-
Amanda: I don't give a shit what you like. You're a sociopath. And I'm shutting you down if it's the last thing I do.

Ali, you're right. It's crazy how things change. For a long time, I didn't have much direction in my life. But then things got better. I met a kid who needed some help. So I got back into karate and became a sensei. There were ups and downs. I even gave up for a while. But I can't give up anymore. I have a long way to be a better man, a better father, a better teacher. But I can make a difference in these kids' lives. It's a tough world out there, and I can help them be ready for it. That's what I've been up to. That's who I am. I'm a sensei.

Chozen: Your sensei is a man of great honor. I can only hope to be like him.
Daniel: Hey, you only did what your teacher told you to do.
Chozen: After our fight, I felt great shame. I wanted to die. But my uncle saved me. He gave me a chance to prove myself. I spent my life trying to do just that but regret is sometimes difficult to overcome. 

Sam LaRusso, where are you bitch?

Cobra Kai Quotes

Miguel: Tory's had a rough life. Her mom's sick and --
Sam:- everybody's got a sob story. Doesn't give you the right to be a bully. 

Sam: I feel so guilty. 
Daniel: It's not your fault. All this started before you were even born. If not for me and Johnny there wouldn't have been a fight in the first place. This is my fault.
