I'll only be 20 this year, but I basically do the same thing as you. I started training a lot, because I don't have to speak too much. I just listen to my coach and do what he tells me to do. He is chill and everything, but he knows I don't like to talk. I also study a lot. I love my faculty, and my dream is to stay in academy. I basically go to Uni, go to training, sleep, repeat. I'm pretty happy with it. I would probably do the same even if I didn't have a stutter. The only doffrence is that I avoid talking as much as possible.
