That's one hell of a story of hustle. What you've discovered, I think, is (paraphrasing Steve Jobs [1]) that the world around you was built by people just like you. You've seen behind the curtain, and there's no wizard, only some dude who's no smarter than you are figuring it out as he goes along. Kudos to you for discovering this at such a young age, I didn't get it 'till my twenties.

My advice to you: put the last section of your article out of your mind. You've achieved some pretty amazing things, focus on that, and keep shipping. Comparing yourself to others is a path to insanity, there will always be someone who has accomplished more, done it faster, made it look easier, etc. And one more thing-- you're never too young to do anything, but keep in mind that with age comes experience. There are people out there (like the ones you mentioned), who have been where you are before, have faced similar challenges, and overcome them. No matter how early you start, you'll always have more experience the older you get, so continue to seek out the advice and mentorship of those who have walked the path before you.
