I recently installed linux mint 15. It has been a bit problematic.
One problem is that it wouldn't shut down. I had to edit the grub2 config to get it to shut down.
Also, at one point the sound randomly stopped working. Would only see the dummy output. Had to reboot to get the sound back. So I don't think I fully fixed that issue.
I was using xubuntu before, and it's really hard to resize the windows. There's a weirdly small area to click on, which is frustrating. There was also a problem with the right mouse click which needed to be fixed with a config change.
It's just buggy, where I would expect things to work.
I will say, sound issues I've had with every OS I've run, Windows Mac and Linux. Sound drivers are shit in general. Your other issues are completely valid, though I've not had issues like that for about three years now.
This post is sort of defeatist. Definitely, self awareness is important, but I think that the vast majority of talent is from practice and study as opposed to something innate.
Joining a commodity market with a me-too clone, however, would be ill advised. But it doesn't seem like that is the case here.
I do think that the education market is tough. There's so much out there that's free.
