Really interesting essay.
It also made me wonder if the opposite is also a skill you need to learn; do people need to learn how to see happiness when that happens around them? Some people seem strangely blind to happiness, even to their own.
Hmm, interesting point!
On one hand, my intuition suggest that "happiness" is ill defined as a thing to do work here (sorry if it sounds annoyingly mysterious, I'm not sure what that'd mean exactly too!), and thinking in these terms can only take you so far.
OTOH, there's definitely some stuff you can do to push your "happiness baseline" around a little bit, and I think some people from rationality blogosphere had reports on this (Agenty Duck? can't find it).
