I know I'm not smart enough to make it as a physicist. And this isn't going to be another, "Convince me to be a physicist" thread. I just want to know how others approach the problem of simply not being good enough to do something you want to do. I had dreams the last couple years of getting a PhD in Physics and working with researchers and students to solve difficult problems in Quantum Mechanics and such. But I wasn't told the situation for a physicist is bleak. I'm starting my undergrad next fall, and I'm a bit depressed that I'm settling for engineering or education programs instead of going full try-hard as a physics major, but I have to make money when I get out of college. And I'm not going to play a game that I'll be going into with a significant disadvantage. I'm also too inexperienced to really know what I want yet, and that's really disconcerting too. So anyways, how have all of you guys dealt with just not being good enough or settling for something more reasonable? Because I feel really dumb about it.
