Do you guys have any advice or tips on how to create a gang? any book, movie, podcast, link? please

As i said im a 17 yo friendless loser and the only thing i enjoy doing is fighting, i practice muay thay and i love fighting, im quite strong; but ive never created something in my life and i feel a strong loneliness, i think that if i could create a tribe, a group of friends, i could know myself better and evolve as a person, also i wanted to do an activity, preferably a manly activity such as fighting like a fight club, but how can i create that? how to approach people? any tip please?
