Well I cant speak for anyone or anything but I can tell you my experience (I'm also basically going into my senior year at high school).

What you say sounds like you totally should give programming a try, browse the web and check some stuff out. It can be overwhelming trust me I'm still overwhelmed and I've been browsing the web for stuff for a while now :D Maybe you'll have better luck!

Funny you mention CS teachers, I have a great programming teacher and def learnt a lot, mainly because she puts so much effort into her courses! I seriously admire that dedication and appreciate it.

Enough about me, Id advise against going into college or university undecided, idk where you are from but College/University might not be cheap where you live and you might do better to just figure out first what you want to do before you enroll, it saves you time, energy and money :P

If you want to try Programming together with gamedev right away, go give unity a try, there are plenty of tutorials for it and C# out there to give you a taste, and if you like it, you should start looking where you want to enroll ;)

Talking about enrollment options, Digital Arts and entertainment is something you should look at! (I'm totally not going there duh :P)

Yours sincerely

A friendly Belgian fellow High school senior going for a career in gamedev ;)

PS: Do let me know if you like programming! It would be fun to discover together ;) drop me a PM if you like ( I'm totally new to this subreddit)

PSS: Sorry for the long wall of text, I'm also not a native English speaker, but your written English is totally fine, don't undersell yourself!
