From Frank and Theresa Caplan, The Power of Play, about what makes for success in creative professions
To create one must have a sense of adventure and playfulness. One needs toughness to experiment and hazard the risk of failure. One has to be strong enough to start all over again if need be and alert enough to learn from whatever happens. One needs a strong ego to be propelled forward in one's drive toward an untried goal. Above all, one has to possess the ability to play!Ms. Rabett calls Eli's lab his toy chest. He mutters about her stash taking over the house. Live safely, die bored.
