I feel as if commenters have not read the blog post in the same way I have.
More than anything, what a self-starter community-taught coder needs is motivation, curiosity, and access to resources. It does not matter where you begin, so long as you have enough stuff to take the next step.
OP, as you've said so yourself, the places you can go are vast! And it's no small thing to have already made working things! Now is the time to play, discover what you like and don't like, start projects and abandon them, go down rabbit holes, get stuck and frustrated, to over-romanticize, to become bored, to feel like an imposter, to become jaded but then to be inspired again, and to experience the magic of making.
I wish you luck and thank you for sharing. I'm excited to learn from you!
Thank you for your kind words and motivation. I would like to experience what you have talked about here.
