It's not all good. There is tremendous suffering in the world. So many of us have to bear the burden of so much. There are bombings and starvation, layoffs and abuse, intractable poverty and senseless violence.
To experience happiness in our daily lives does not mean hiding our heads in the sand. It's not about feeling absolutely wonderful all the livelong day. We're meant to feel bad as well as good – the part of our brains that experience, fear, worry, sorrow and anger is there to protect us from danger and spur us into action. When a speeding car is bearing down on you, it's not too smart to think, "Isn't that good?" Rather, you feel fear and get out of the way.
