Ask HN: What is the best way to spend my time as a 17-year-old who can code?

I'm 17 and I can code at a relatively high level. I'm not really sure what I should be doing. I would like to make some money, but is it more useful to me to contribute to open-source software to add to my portfolio or to find people who will hire me? Even most internships require you to be enrolled as a CS major at a college. I've also tried things like Upwork, but generally people aren't willing to hire a 17-year-old and the pay is very bad. Thanks for any advice!
