My take on this is pretty much the opposite. . . .
This is why advice is so . . specific . . to the individual giving the advice. After I dropped out of college, I spent years working, living life, reading philosophy books, talking with people who seemed to make sense, doing workshops, trying stuff out, and learning. By the time I went back to school (8 years later), I had my world view and life approach figured out. And I needed the most direct line to marketable, hard, technical skills. Hence, my personal take on it.
When people ask for advice, I think the best thing is for someone to tell their own story, their reasons behind their conclusions, and the other person can think it over and decide what would work for them.
And the real goal for anyone is understanding and knowing themselves truly.
Your story is really interesting. And I love hearing people's stories.
Your point about being self taught is very good. When I was managing big IT projects, my best technician was a work-from-home single-parent mom with 2 young kids. She was, by far, my best developer and technical person. Whenever I was in town I would always take her out to lunch. One day I asked her from which college she graduated. Turns out, she did not even have a high school diploma. I was floored. As a kid, she hated high school, was bullied, and was actually roughed up by some high school bullies. She told her mom she did not want to go back to school. And her mom said OK she could just come to work, at a high tech company, with her. So, from age 15 she was self taught working at all these high tech companies. And her tech skills were far above any of her peers. Isn't that an interesting story?
