If you've ever been jealous of someone, the last thing you want to do is tell them that you think they might actually have something over you, or that they might succeed at the thing you wish you could, or that you wish you could paint like that.
And yet, if you're jealous, the only reason you are is because you actually think those things.
So, the next time someone is jealous of you, and starts spreading the kinds of things that jealous people spread, remember that it's a compliment: they believe you actually might be able to pull it off - and that drives them crazy.
And, the next time you are jealous - and I've been a professional for many years at being jealous - find your strength. You actually aren't jealous of them. You are simple scared of your own fragility about who you are or what you are doing. Work on that, the jealousy will fade soon after.
