As a white belt while i'm sparring, sometimes i'll get mount but i remembered reading here that white belts shouldn't learn how to submit yet and just learn more about positioning. I've been doing jiu jitsu for atleast 2 years now (on and off) and have been following what people have said. To learn how to escape and position rather than submiting. Problem is, i can't submit for shit now. all i try is americana if that doesn't work, i just try to squish them more until they get out. So what do i do? I'm kind of confused. Do i work on submissions now or just more defense? Should I not worry about submissions?
