Is it worth it?

Hey y'all. Just secured a 2024 SA gig at a BB. It kinda hit me right after the offer. Is this it? Was always a decently bright guy growing up but never really applied myself, skipped class and was an idiot in HS. Went to a shit college and decided I was going to turn it all around, found banking through the advice of upperclassmen I knew. Even though I came from a family that never had to worry about money, the fact that people told me how hard it would be to break into IB from a non-target made it all the more enticing to go get some fat paycheck. It became a challenge to get the spot more than it was an actual desire to go into banking. It felt good these past few years finally working hard, gaining leadership positions in extra-curriculars and doing research with professors I grew close to, but after securing the offer I asked myself "what next." Getting the job wasn't enough, I had fallen in love with the chase. Everybody else was super pysched for me but I realized Idgaf about this job or career. I lay in my bed late at night wondering if this is all I was meant for. Did I really trick myself into thinking that what I was doing was worth it because it was tough to get or should I have done something else that is actually dope. I am a math major, and I would've loved to be a mathematician/physicist, teacher or conservationist but my ego stepped in and decided I wanted to be the big shot from my home town going into banking. I haven't even hit the desk yet but I feel as if I am selling myself short. Am I just some idiot that grew up with the privilege of not having to worry about the bills or does anybody else every feel like they meant for more than pushing around numbers to make the corporation huge sums just so I can get a small sliver that is a lot more than most other people. Lmk. I am still planning on atleast interning and really getting a taste before I make any big changes but I feel like a madman figuring just 8 months ago I would've given anything to be in the spot I am in now. I probably am crazy but ya, I wonder if there is any other crazies' out there with me.
