"One time, I got real angry because we were supposed to go hiking, and a flash flood washed out the trail. My mentor, he pointed out that if I was mad at the storm, I'd be mad forever, 'cuz there's no getting your own back on that, I can just shout at the cloud until I turn blue as a troll. So I thought about it, and later when we went out, there were new rocks washed in I would'na seen otherwise. So there's no use in getting mad at some things."
