You can't take your stuff with you when you die. That doesn't mean you shouldn't enjoy it while you're alive. Why not? But it's all pretty silly. I fall victim to it. I mean, I want nice stuff too. So I guess I'm poking fun at myself as well as other materialistic people.
Failure's hard. There's no way around. Bombing on stage never feels great. You feel judged, you feel alone. But then when your performance works, it's transcendent.
