Becoming Pro

Hey, I have a question that’s been on my mind for a long time. I’m 19 now, but when I was 15-18 I was really good at Rainbow Six Siege and a pro-level player. The problem was that I always played solo—I never had a chance to join a team. Eventually, I quit, got a job, and started focusing on my life. Now, I’m in Germany, studying abroad, and I really regret quitting. I keep thinking that if I had pursued the professional gaming route, things might have been easier for me, and I could have built a career. So now, I’m not sure what to do. Should I continue focusing on my studies, or should I get my PC again, start playing, and try to join a team? Maybe I still have a chance to become something. What do you recommend me to do guys
