Play is distinct from ordinary life in its seclusion from ordinary life. Play begins and then it is over. It has its own space and time. It is an oasis.
People who feel they need to show that they are decisive are not as creative because they are not willing to stick with the problem longer. The ability to live with the discomfort of the unknown and undecided is a factor in creativity. This would relate to the Jung’s personality types. The feeling of whatever happens it’ll be okay. So there is a trust in play that leads to creativity.
