Many of us feel/felt that way. I guess it depends on what you planned on studying; certain career pursuits require a college education such as legal or medial. But I’m pleased to see your ambition and drive has given you the tools for a seemingly bright future in tech. I’m currently learning to code, but I have the whole cumbersome responsibilities aspect of a full-time job, student loans to pay off, mortgage, etc…while I’m doing it. Plus, I’m 2x your age. Better late than never I guess.

Keep doing what you are doing! It’s impressive.
