I can't think of when I've had someone be envious of my writing or drawing. If they have, they've been quiet about it
People would come to me for help sometimes, but there's been no jealousy I could see.
I'm usually on the other side. It's hard not to get jealous, when you see amazing work. My jealousy manifests weirdly, though. I'll start gushing about their work, and looking at everything they've done, trying figure out how they got so. damn. good.
I've had friends turn nasty or jealous about other things in my life, though, and they'd say some pretty awful things in passing. Things aimed to bring a person down. I'd always ignore it and keep on as though they'd not said anything, like absolutely refusing to show any reaction. Or I'd turn it into a joke. Or, if it was in front of a group of people, I'd be super nice and just let them expose themselves, if that makes sense?
And my investment in their opinion or company would go down and down, until I'd just close the door on that relationship. Life's so short, you know?
There's bigger fish to fry.
