"The third form of happiness, which is meaning, is again knowing what your highest strengths are and deploying those in the service of something you believe is larger than you are. There's no shortcut to that. That's what life is about. There will likely be a pharmacology of pleasure, and there may be a pharmacology of positive emotion generally, but it's unlikely there'll be an interesting pharmacology of flow. And it's impossible that there'll be a pharmacology of meaning." Kind of interesting, eh?
