Related to the Wil Wheaton post (keeping in mind that 'happiness' is not the opposite of, nor the cure for, depression and anxiety). So what are the three things? First, "The first mistake that people make is equating happiness, the overarching quality of life, with the temporary enjoyment we feel in response to something pleasurable." Second, "people enjoy what they are doing more if they are focused on what they are doing, right when they are doing it" (the thing I really enjoy about giving talks is that they uniquely allow me to be in the moment as I speak). Third, "it takes commitment to strengthen and reclaim the function of our core “pro-social” demeanor—to learn skills around trust, reconciliation, and teamwork." The idea that these are skills - not innate amibilities - is key. So is the idea of reclaiming the ability to do them after a major setback.
