I get that the point of the post is to encourage others, but proclaiming to have "learned how to code" feels misleading because there is no real finish line for it. This is an open-ended skill, there is no such thing as being done with it, same with most other skills. Maybe you can claim that you self-learned how to do a Rubik's cube, but I have been learning how to code for 15 years and with each day I feel like there's so much more that I don't know.
