" What we pay attention to affects more than just our inner experience, because those thoughts don’t just stay in our heads. What we think directly influences what we feel; our thoughts and emotions cannot be separated. We cannot just choose to feel happy or relaxed or excited or mellow, because those emotions are rooted in our thoughts. What happens to us is often out of our control. But what we think about what happens determines how we feel, and subsequently, what we do about it. "
