english: 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.
non_english: I kako bih konačno odgovorio na to pitanje... u tim studijama, od pre 40 godina, tražio sam kreativne ljude, umetnike, naučnike i druge... trudeći se da razumem šta ih je to tačno ubedilo da je baš to čime se bave vredno ulaganja, zašto se bave nečim od čega, u većini slučajeva, ne očekuju slavu ili bogatstvo, a opet imaju osećaj da rade nešto značajno, i u tome vide smisao svog života.
