Since when is accounting oversaturated?

I don't know.

I'm 19 in my third year of uni. Here's what I would've done to figure out what I actually wanted:

First, look at viable courses. Look at your family connections, see anyone you might want to get closer with. Ask them about the industry. Then:
>Read textbooks on the subject. Torrent them free. Reflect on yourself after finishing a chapter and see if you like it or not
>Watch online lectures. Torrent them or whatever. They're everywhere and I use them to put myself a month ahead of everyone else.
>Pick up different kinds of information on a subject. Like if you're interested in Japanese, listen to podcasts, read manga, watch anime, watch Jap gameshows, etc. so you always get fresh perspectives.
>Ask for a syllabus in a subject you're interested in and try to finish the introductory work of it

After four months of that, you'll be in a pretty good place to know what you wanna pick up. But you've gotta be consistent and capable of managing yourself. That's going to be hard seeing that you dicked around in high school.

I finished high school at 16. I'm gonna finish college at 20. I do wish I spent more time figuring it out, but this is fine too.
