I find that the great artists I've met are people who are so playfully invested in their process that, even if it doesn't come out the way they like, they still power through and even take energy from it.
I think when you get to export your creative impulse into something, it kind of lessens that busy energy that can be so confrontational and pissy.
The one thing I noticed retroactively was that the energy at those Trump rallies was off the charts compared to the Hillary Clinton rallies. The Bernie Sanders energy was as good, gentler, but there was a real passion there.
