My education is entirely self-taught. That really doesn’t make a whole lot of sense, does it? How can you teach yourself something you don’t know if someone or something has not brought that unknown to your attention? Learning without having a teacher is kinda sketchy to me too. Informally learning, that I can get with. A teacher doesn’t have to necessarily be a person or a being, it can be anything that gets you where you weren’t before that object was in front of you.
That all being said, you could be the smartest person in the world and still be a dumb as a two sided box or rocks.
