Although I'm physics and astrophysics (3rd/ 4th year or so as I've changed majors a few times) on paper, i.e. per my transcript, in truth, I've done a lot more math courses than physics ones. I've also more or less completed a minor in economics. I came from a finance major background, and this could not have been more unrelated to my life's passions and interests. I made a mistake, but I was young, and we all do. Furthermore, I've run businesses, so at least I can complete some studies in economics to put on a resume.
However, I'm beginning to lose a bit of passion for physics as I'm truly 100% loyal and passionate towards pure mathematics. While I do love physics in general, the fact is that I mostly love it because of the math. Furthermore, because I've completed advanced math courses but I am not advanced in the physics labs, I find myself lagging somewhat in the laboratory work. I like to learn "truthful" facts, and with math, I feel that I am constantly proving and focusing on truth. With physics, however, I sometimes question whether I am learning factual formulas or theories, or whether the things I learn today will be re-proven incorrect in 30-50 years from now. Additionally, I was going to pursue both physics and engineering or physics, math, and computer science. Once upon a time, I wanted nothing more than to do experimental physics with my life, but now I hesitate to dream about this further, because my lab work is mediocre. It seems that biologist and chemists do the physics lab work just as good as myself, which makes me feel embarrassed.
So, I feel that I have narrowed down my choices somewhat as I'm stuck between a "more physics" route or a "more math" route. Everyone tells me that I love physics with everything in me, which is true. However, I only love it because of the math. I do love learning about atoms and all, but without a superior quality of lab work, my experimental physics choice seems a little lofty. Should I switch over to math, or should I instead persist and become better at lab work while I can? Is it normal to lose some passion, and to become jaded over time? Would appreciate advice from those who've gotten it more figured out than myself.
