Art is about having fun
When I make art, it has to be in a childlike way, without rules, instinctively, to have fun, to create. It's important to have fun in life. Forcing yourself only leads to suffering. And suffering teaches you nothing. I enjoy drawing and painting, so there's no need to look for other artistic activities.
It's absurd not to have fun because it doesn't bring in money! Having fun makes you happy. It's also the only way to the best creativity, the kind that could be useful to humanity. And if it leads nowhere, who cares? At least I will have had some fun!
