I'm 17, and for me, school has always been easy. Never had to study, easily get good grades. Problem is, I now need to be able to study, as I can't learn the stuff I'm doing instantly like I've been able to my whole life. I try to do homework but I'll do about 1 question then go on my phone for 3 hours. I don't have this problem with working out, I can get up early in the morning when it's cold, I take cold showers and shit, its only schoolwork I have a problem with.

I've tried not going on my phone, but then I just think for 3 hours. That sounds retarded but I do that all the time, just think about shit.

I know I just need to get stuck in and do it, but I dont know how to do that.
