In terms of the age thing, I get it. At 19 I hated being at school because I wanted to be making $20+/hour working on websites. But now at 25 and right under 6-figures, I see that I can simply work during the day and then go to school at night. It just means I have to do that for 4+ years. I started at 24, but I will not be done until I am 30. So, if I would have done it right the first time, and not dropped out, I __might__ have been further.
I don't regret it tho. I rolled the dice and although I was trying to hit the start-up lottery at that age (why I got into programming), I ended up on a great career with incredibly valuable experiences that I would not have had if I didn't drop out at 19.
8/10 would do again.
