the value of this is most easily demonstrated in daydream scenarios. I'm guessing that other people, like me, find themselves going through some of the same fantasies time and time again, whether they be about wealth, sex, prestige or whatever else. A few days ago I banished all these familiar fantasies and spent some time thinking up new ones. Not only was it a wonderfully fun exercise, it seemed to increase my creativity when doing other activities throughout the day.
