I love that you are considering how egotistical you are at 13. You seem like a really emotionally intelligent person which will serve you, by the way, so well in the software industry. Make sure to never neglect learning about who you are as a person emotionally; its an investment that will take you much further than just technical skills.

How about writing a blog? You are clearly already a good writer. I'm an author and writing helps me clarify my thoughts and has spurred my growth in ways that is complementary to my technical development.

I wondered when I checked out your profile and involvement on repl.it if you didn't have a blog and/or didn't host things on your own servers if this is because this is challenging for a 13 year old who does not have access to credit cards, etc?
