arguing as wasted time and energy

Interesting thing I read in an interview with comedian/actor Patton Oswalt. The guy comes off as an enviably well-balanced fellow.

"I think one of the good things about getting older is, I just listen to all the arguments and nod my head and go, “Oh, that’s interesting.” And then I just do what the fuck I want to do. So a lot of my friends would lecture me about the home birth, or say, “Oh, you can’t vaccinate your kid.” And instead of going, “Oh, you’re such a fucking moron,” I would just nod my head and say, “That’s really fascinating.” And then we went ahead and fucking had it in the hospital, and booked a luxury suite, and said “Fuck it.” Dana Gould had this bit where he said, "In the time that I would have spent arguing with my friends in the past, I go get an ice-cream sandwich and just sit and enjoy that." Because at the end of my life, I’ll go, “Oh, I enjoyed all those ice-cream sandwiches when I wasn’t arguing with anyone.” I’ll just quietly do what the fuck I want to do."
