One Dilbert Blog reader noted that current research shows that happiness causes success more than success causes happiness. That makes sense to me. There's plenty of research about people having a baseline of happiness that doesn't vary much with circumstances. And given that happy people are typically optimistic, energetic, and fun to work with, I can see how happiness would lead to success.
