I dropped out of school during my sophomore year of college. I was a little bit scared to do it, but I followed through because I was certain that I didn't want to get a normal job or do anything else that would make use of a degree. Dropping out was one of the best decisions I've made, and it pushed me towards the life that I really wanted to live.
However, just because dropping out was right for me doesn't mean that it's right for everyone, or for you. I think that the school system is trending towards obsolescence and is a far worse value proposition that it was in previous eras, but that doesn't mean that it's worthless or that it's not the right choice for a lot of people. You might be surprised to find out that when people email me to ask if they should drop out, I tell many of them that I think they should stay in school.
