It was a good read until he started with the art is a skill and anyone can do it. He's kind of in his bubble there making assumptions about people. People have various levels of aphantasia, it's not binary. Those that are good at visual imagination do art, people without can't draw a fucking apple from memory reasonable art is beyond many, even if they had the time to dedicate to it.
Everything else he said was on point. well eventually on point, that was a long ride.
Edit: Man, look at all these talented people telling me I could be talented too if I just tried. Some of you might find a shocking revelation in thevfact that not everyone has the ability to perform the skill you perform. Some people, like me, have put several thousand hours into trying to improve my ability to draw, and while it has improved slightly, I am still not capable of drying anything above rudimentary. Talented people find it easy to project their skill onto other people but that's not how it works. It's not just a feeling that you can't do it, it's trying for years and not being able to do anything appreciable with it. My seven-year-old had more skill out of the gate than I had after scoring around with it for 30 years. So keep on telling me that I could just do it if I'd just invest the time and make yourself feel better that you invest at the time. That's truly helpful to me.
