A few days ago, I came across an article espousing the benefits of auto-didacticism (the art of self-directed teaching and learning). I found myself nodding in agreement with some of their points but they were hidden behind a much longer rant about the evils of formal education. I've seen a lot of hate on the topic of formal education lately and while I kind of understand it, particularly with the current state of US education, I don't think it's a very fair assessment in most cases.
I'll preface this by saying I'm an Australian, whose university (college) education was paid for by the government, with no expectation to pay it back until earning a reasonable living wage. I'm aware of the financial burden that people in other countries experience in trying to gain an education and have tried to be mindful of this, however as always, your situation and mileage may vary.
I studied illustration design at university, digital painting at a concept design school, and have self-directed my own learning using online resources (such as Drawabox). Each of these offered something different and had its own pros and cons to contend with.
