I dropped out of high school at 17 and went to college (which I think is the same as a community college in the US? Not a full four-year degree) when I was 24 for programming. Worked as a programmer for a couple years and then got bored and went into agriculture for a couple years. Now I’m bored again and looking at going back to school for something else. I’m 33 and I’m doing fine. 21 is so young! You have lots of time to figure yourself out. Honestly I think asking 18-year-olds to decide what they want to do forever is ridiculous. Almost nobody knows themselves that well that young. I’m still figuring out what I want in life.
