I don't know if this should be posted here, and I doubt if anyone can actually write anything genuinely illuminating, but I'll post it anyway, as self-treatment at least. To me it is a career question, and a very fundamental one too. Most of you probably don't have these kind of problems, as usually there's at least some correlation between how skilled/able one is and how much he/she enjoys the topic. But not for me. While I don't suck at physics, I am not too good either. In particular I have problems with mathematics (both as a physicist's tool and as a science of its own). And I have never really grasped things like electric circuits or certain topics in mechanics. I can usually, but not always, solve the exercises we're given, but this feels like a mechanical procedure, and I too often feel I don't have that real insight I'd wanted to have. I feel uncertain, constantly thinking whether I've got it right or wrong. And I never feel my solution is correct unless I get to see the right result. My uncertainty is probably just an offshoot from the fact that I don't really understand many things in physics, so that it is justified or rational uncertainty. I am no more than an undergraduate at the moment. As long as I have understood anything about real physics, I have wanted to be a physicist. And while I don't have what it takes, physics is the target of all my affection :!!) But no matter how much I daydream, my brain cortex won't double. Now matter how much a person with a wooden leg exercises, he will never win gold in hurdles in Olympics. Now matter how much a blind person studies, he can never become a surgeon (hopefully?). That is not to say that there's as much hurdles gold metalists as there are physicists, but to say that to want something badly just may not be enough. So, is there anyone else like me on the forum, or do you know anyone? What to do? What have you done? Continuing physics as a hobby? I don't think so. I'd never get over the fact that I'm an amateur, so it would probably be better to leave physics completely. Well. I think I have already answered myself, but I'd gladly hear, if there are other with similar but possibly milder feelings about physics. And I don't expect for you to write anything unrealistically encouraging. I know not everybody get what they want. Thanks for your comments (and flames, too) in advance!
