A few years ago, he began looking at getting into law school.On Instagram, the 26-year-old athlete shared:“Five years ago when I won in worlds. In my mind, I was like, oh, I'll just go to law school now. I wouldn't be in jiu-jitsu anymore. I'll just have another career. I didn't think that you can make a career in jiu-jitsu like that. That was a standard way to think back then."But the popularity of Brazilian jiu-jitsu grew so quickly that he kept at this sport and now it's his full-time job. He continued:"But then all of a sudden, jiu-jitsu exploded. And now there's so much opportunity for everyone. So you can really just live your passion. It's so cool.” View this post on Instagram Instagram PostMikey Musumeci is living his dream as a Brazilian jiu-jitsu athlete competing in ONE Championship.
