I'm im the same camp. I've start studying at a university a few times now, and I keep failing because other oportunities come up that are more important than passing the course.

I need to be able to self study at my own pace according to how my free time allowes. I'm also not that interested in formal tests and exams. And even course projects.

I want to learn what I need for whatever project I'm currenty working on or going to work on next.
