And to start those studies about 40 years ago, I began to look at creative people -- first artists and scientists, and so forth -- trying to understand what made them feel that it was worth essentially spending their life doing things for which many of them didn't expect either fame or fortune, but which made their life meaningful and worth doing.
E per cominciare a farlo -- con questi studi, circa 40 anni fa, iniziai ad osservare persone creative, in principio artisti e scienziati e così via, cosa gli facesse credere che valesse la pena passare la loro vita facendo cose per le quali molti di loro non si aspettavano né fama né fortuna, ma che rendevano le loro vite significative e degne di essere vissute.
