The trick is knowing when mindfulness is called for and when it’s not. “When you’re staring out the window, you may well be coming up with your next great idea,” he said. “But you’re not paying attention to the teacher. So the challenge is finding the balance between mindfulness and mind wandering. If you’re driving in a difficult situation, if you’re operating machinery, if you’re having a conversation, it’s useful to hold that focus. But that could be taken to an extreme, where one always holds their attention in the present and never lets it wander.”
Epiphanies emerge when you let your mind wander. But mind wandering also gets in the way of learning and getting stuff done. You just need to be able to dream and focus when you need to.
