It’s always easier to get a degree the more credentials and degrees you have. If you can afford to go to college, I always recommend it.
I’d recommend to start applying for jobs now and see if any employers show any interest based on your current experiences and willingness to learn. If you don’t get any bites with what you know now it may take quite a bit more learning on FCC and elsewhere before employers want to take a risk on a young or inexperienced hire.
A Computer Science degree would open a lot of doors. A lot of people debate about the value versus costs of college, but overall I think the majority would still recommend college (especially for a young person), if that’s a viable option.
I’ve seen many companies offer tuition reimbursement. Maybe you could look for one of those jobs and start as an intern while going to school?
Best wishes in whatever you decide.
