I'm a second year grad student within engineering physics and after this I am going to take a master in theoretical physics. My plan is to go even further with a PhD when I am done. The thing is, I really don't enjoy some parts of my education. I love the theoretical part of almost everything, I am really good at very abstract math and physics but I feel that classical mechanics is one of the most boring things I have ever done. The theory and derivation of it is fine but when it comes to the problem solving it feels like the only thing I am doing is reading some 400 years old methods and repeating it. So my question is, do you need to like the whole "package" to be a good physicist or is it normal to feel like this about some areas in the field?
