I have a lot of fucking problems, what's the best form of combat to beat their ass and show them who's in charge?

Judo is Japanese for "easy way", it's a martial art invented by a sickly guy who still wanted to be a competitive martial artist. Its Always my go-to recommendation for people, especially considering the philosophical underpinnings sort of match with your goal of dealing with your fucking problems where the grappling moves could help.
Awesome, this will definitely help me to defeat those fucking bastards
I carry a pair of these with me most places. Judo and jujitsu are best for one in one fighting for sure. But usually in every day life walking about you don't get to pick a honorable opponent and it is more likely gonna be like four ghetto rats all sworming at once. For those it's best to have a weapon and be intimidating to begin with.

This is an excellent suggestion. I'm gunna use these as my weapon of chose and play karate movies to the set the tone for the death that awaits them
