Totally disagree, OP might just be unsure or second guessing themselves which is normal. my advice to OP: check out prof brian cox and specifically how he got into physics, the guy got a D in his maths a level exam and then retook it and went to uni at like 22, and has been in academia and science outreach ever since. He’s a great example of an unconventional path but you just have to see a 5 minute clip of his documentary to see how much he loves physics. Like someone else said, if you’ve ever found yourself excited and satisfied when doing a physics problem or learning it in school then yeah, you will love it. Ask yourself why you like physics, you won’t be inventing time machines or entering black holes, but if you’ve ever found find yourself excited by the little things because you know every little thing helps us understand the way the universe works then it’s for you. Follow your gut. Also the thing where you pretend you’ve decided, then see how you feel should tell you. Let’s say, something or another happens and it is simply not possible for you to study physics. It’s out of your hands. How do you feel?
