Choose to be optimistic, it feels better. - Tenzin Gyatso

There are four independent brain circuits that influence our lasting well-being, Davidson explained. The first is “our ability to maintain positive states.” It makes sense that the ability to maintain positive states or positive emotions would directly impact one’s ability to experience happiness. These two great spiritual leaders were saying that the fastest way to this state is to start with love and compassion. The second circuit is responsible for “our ability to recover from negative states.” What was most fascinating to me was that these circuits were totally independent. One could be good at maintaining positive states but easily fall into an abyss of a negative state from which one had a hard time recovering. That explained a lot in my life. The third circuit, also independent but essential to the others, is “our ability to focus and avoid mind-wandering.” This of course was the circuit that so much of meditation exists to develop. Whether it was focusing on one’s breath, or a mantra, or the analytic meditation that the Dalai Lama did each morning, this ability to focus one’s attention was fundamental. The fourth and final circuit is “our ability to be generous.” That was amazing to me: that we had an entire brain circuit, one of four, devoted to generosity. It is no wonder that our brains feel so good when we help others or are helped by others, or even witness others being helped, which Ekman had described as the elevation that is one dimension of joy. There was strong and compelling research that we come factory equipped for cooperation, compassion, and generosity.

If we think only of ourselves, forget about other people, then our minds occupy very small area. Inside that small area, even tiny problem appears very big. But the moment you develop a sense of concern for others, you realize that, just like ourselves, they also want happiness; they also want satisfaction. When you have this sense of concern, your mind automatically widens. At this point, your own problems, even big problems, will not be so significant. The result? Big increase in peace of mind. So, if you think only of yourself, only your own happiness, the result is actually less happiness. You get more anxiety, more fear.

What we do and think in our own lives, then, becomes of extreme importance as it effects everything we're connected to.
