But the value of daydreaming does not stop here. It has been found that it improves a person's ability to be better adapted to practical, immediate concerns, to solve everyday problems, and to come up more readily with new ideas. Contrary to popular belief, constant and conscious effort at solving a problem is, in reality, one of the most inefficient ways of coping with it. While conscious initial effort is always necessary, effective solutions to especially severe problems frequently occur when conscious attempts to solve them have been put off. Inability to relax, to let go of a problem, often prevents its solution. Historically, scientists and inventors are one group that seems to take full advantage of relaxed moments. Their biographies reveal that their best ideas seem to have occurred when they were relaxing and daydreaming.
