Mr. Russell is a great believer in versatility in all creative work. In any physical work he believes one can work many hours at a time, but in mental, creative work he believes one can do his best only for two hours at a time on any one subject, but he can work another two hours on another subject with equal freshness. He therefore sometimes works two hours a day on each of five different creations, and in that way can live five lives at a time.
