I think about any trade that creates value.
Let’s say I’m a hairstylist. I do videos on color techniques, q+a, product reviews and etc.
It doesn’t have to be just the painting. It’s everything around the painting. All the details can be monetized in a way. Although not as easy like you say.
I’m guessing you know a thing or two about this so I’ll just stop there. Lol
