Bill Cunningham New York

Movies are rarely about happy people, but a new documentary called Bill Cunningham New York is an exception.  It's about a man who does what he loves, lives a simple but interesting life, and is simply happy.  I haven't seen this yet, but it would be interesting to approach this documentary from a Stoic perspective to see what must be an exemplary lifestyle.

This makes me wonder.  There are of course some Stoic methods of increasing happiness, such as living in the moment and rejecting greed, fame, lust, and other forms of harmful desires.  I wonder if chronically happy people are similar in adopting these principles.   It seems likely to be true on average, because how could someone be truly happy if, for instance, they always wanted more money?  But I'm not aware of any actual study that's been done that confirms this.  Does anyone know of any?

It reminds me of the famous opening lines of Anna Karenina:

All happy families resemble one another, every unhappy family is unhappy after its own fashion.
