Lex, thanks a lot for your empathy, I really appreciate it because my adolescence was pretty rough because of this topic. I was seriously interested in physics during my teenage years and i wanted to be a theoratical physics. Then i had a friend from high school that pretty smart can grasp concepts faster than me. At a certain point I began to be unable to understand the theoretical physics concepts but he understood it very easily. I got depressed and spent my adolescence with severe depressions and anxiety because of my biological limits. It may sound simple from the outside but it's hurtful for a teenager who dreams big. Intelligence is real privelege that nobody talks about.,(reply>), Trust me... High IQ isn't all it's cracked up to be. The more one knows, the more shit one also knows!,(reply>), @CrikeyZZZZZZZ,(reply>), It’s always possible to build your level of intelligence, comparisons never help anyone. Your level of intelligence is like a staircase and you’re in the middle of it climbing, just cause you see someone is 10 steps ahead of you it doesn’t mean you should stop climbing. You won’t be able to jump to that point the other person is at either but stagnating will only leave you at the level you’re at, you can always take that next step,(reply>), Your story in its overarch was exactly mine,  depressed anxious for same reason,(reply>), LMAO.  If not having a propensity to easily become a theoretical physicist put you into a cycle of depression and anxiety that ruined you, what did you end up as? (except a burden to others).  You do realize that probably 2% of the population could be theoretical physicists.  90% of the population could never pass a single college physics course without grade inflation.    Have you looked into basket weaving?
