I’m starting to wonder if I’m actually smarter than I think I am.

I’m not here to brag or anything like that. I’m personally just very confused as to what the heck is going on. I’m in my mid 20s, and I’m in my second year of law school in the US with a full time internship in regulatory compliance. I’ll be graduating in a year, I’m taking the bar in February, I’m in 2 study groups, I’m reading for fun for the first time in 3 years, and I somehow magically have 4 hours a day for the gym. I may be completely delusional in this thought, but I feel like at 25 I should be burned out, especially with my schedule. Also, I’m not super organized, and I don’t have any sort of schedule. I legit am not burned out though, and I actually feel really great. My grades are good and everything else is good as well. I guess I’m just confused as to how I’m handling it all so well when I’ve always struggled. I feel like it’s only a matter of time before I burn out. So I guess this is my question: how do I know if I’m actually good or if I’m on the verge of a nervous breakdown?
