It's been more than 20 years since I left high school and I've had a very good career and life despite having no degrees and a piss-poor high school GPA, because ultimately none of that actually matters in the real world. All that matters is who you know and whether you can do the job. If you know people who will give you a chance and you can actually succeed at the job, you'll do fine. Learning actual skills that other people care about and value is far more important than being able to regurgitate bullshit for a test to get a piece of paper that's meaningless. My only real regret is that I didn't just drop out of high school and get my GED so I could focus more time on my side-projects at the time.
