Nobody is as happy as the person who is both very impulsive and very lucky.
I mean it's not some new discovery.
It was obvious for the attentive observer that Sinatra had lived a happier and more interesting life than Rockefeller.
Similarly Hugh Hefner has lived a more fulfilling life than Charlie Munger.
You gotta live in the moment and be impulsive to be happy. But to sustain those levels of impulsiveness you need luck to go your way to somehow always manage to avoid the negative consequences of impulsivity.
Whether it's some Mafia boss looking for a revenge after having been diluted from the record publishing partnership or some disgrunted Playboy bunny going on a media blitz aiming to gain a huge amount of money...both men needed a huge amount of luck to avoid being taken down.
