Beautiful quote. Reminds me of a scene in the documentary

jiu-jitsu vs the world:

Renzo Gracie: 

"I asked my dad: 'Why do I have to train so much? I train twice a day. I train

in the morning. I train at night. Every weekend, I go train.' He goes 'My son,

you train if one day someone tries to bully you, someone not letting you express

your idea, don't let you be yourself, you are gonna be able to defend yourself.

Or maybe if you become a prick. You become a villain, and you want to oppress

someone, you want to bully people, you want to be a jerk, you want to make sure

you know jiu-jitsu so that they won't be able to defend themselves. Or they

won't be able to be rebellious. Now you choose who you want to be. You want to

be the nice guy or you want to be the bully. It's gonna be up to you but

jiu-jitsu is gonna help you either way.'"
