@foone wow! Your phrase summarized it very nicely. It's true because I do programming for the money, but from time in time, I just do things for fun like the Ray Tracer in a boot sector https://youtu.be/Njtn_1jBa9c?si=oW3hqYtjsw0e-aQV and the Bob Ross comparison made me smile, because I thought in adding the happy word to my thinking discourse "wow! We can save a register here if we move this happy register there and we avoid a pop, now the stack looks like a happy stack, and we saved a few bytes. It's the little joy."
