What ways to make us happier?

Politicians are looking to the dismal science for ways to make us happier-
but is the well-being state a bad idea?
Think about what would make you really happy.
More money? wrong. 2.5 smiling, well-adjusted kids? wrong again.
Now think about what would make you most unhappy:
losing your sight or a bad back.
The fact is, we are terrible at predicting the source of joy.
(Sex is the big exception, but you get the point.)
And whatever choices we do make, we likely later decide it was all for the best.
