I've spent an inordinate amount of time learning stuff on the Internet. People always call bullshit when I mention that I learned Japanese online, and often still don't believe me after I list all the resources I used. "You must have taken some classes, right?" Well, I took exactly one 12-hour course, and it was great! But I already had a strong command of the language at that point, and the course was only to improve my speaking (practicing foreign languages alone is not conducive to conversational skills). You actually can learn Japanese, and just about everything else, online.
This seems like an appropriate place to mention that I'm fairly certain that the university system is a pyramid scheme. Students pay absurd amounts of money for a degree, and then realize upon graduation that they still have plenty to learn on the job, and may or may not ever use most of the stuff they learned in college. But they've invested six figures into the degree, so they decide to screw everyone who had the sense not to spend 0.8 Lamborghinis on education by creating entry barriers for those without degrees, thus increasing the value of their own degree. Wow. Way to go, society.
As someone who was a fairly bad student growing up, but a voracious learner outside of school, I'm a huge proponent of skill over pedigree. What does a piece of paper saying you can do something mean if you can't actually do it? What does it mean if someone without the paper can do it better?
Not all tutorials are equal, and the absolute best ones are (in my experience) free. Check out the Zencyclopedia.
