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.
Som start på de studier for 40 år siden, begyndte jeg at undersøge kreative mennesker, først kunstnere, så forskere osv. for at prøve at forstå, hvad der fik dem til at føle, at det var værd at bruge deres liv på at gøre ting som mange af dem ikke forventede  hverken rigdom eller berømmelse for, men som gjorde at deres liv gav mening og var værd at udføre.
