What Makes a Good Life?

I recently came across a long term study that began back in 1938. It was done by Dr. Arlie Bock, a Harvard physician, and it began with 268 men who were sophomores at Harvard between 1939 and 1944.
The goal was to study successful and ‘normal’ men, to see what makes a good life and maybe even figure out a general recipe for success that the rest of us could aspire to.
