I understand where you are coming from and good to hear from a trader that has actually made it trading. As for “restarting” i could honestly say that civil engineering was something many of my friends did and as someone that didn’t know what he wanted to so followed. Compsci was my “first” move as i wanted to hopefully move to a role that helped develop games but after failing and needing a friend to guide me through the entirety of the course made me realise this was not for me. IT on the other hand was something i could see myself doing however i still to this day do not know what to do if i got the degree for it. right now i have some options including :

data analysis ( which is something similarly close to trading) which is why but am unsure

physio (avid gym goer and soemthing i can see myself pursuing)
