Seems like a good time to quit NATO.

I think you’re right… it’s the same thinking that leads to thinking hobbies should become “side hustles” once you get reasonably good at something.

And sure, if you like making cute dingbats and selling them to people, go for it. We could all use a little extra cash anyway. But at the same time, don’t think it any less valid to spend time absolutely not participating in commerce. If your hobby is sitting on a park bench and watching squirrels run around, you’re not less than the dingbat seller.
