Problems, however, are rarely solved on the spur of the moment. They must be organized and dissected, then key issues isolated and defined. A period of gestation then sets in, during which these issues are mulled over. You put them in your mind and consciously or unconsciously work at them at odd hours of the day or night - even at work. It is somewhat analogous to trying to place a name on the face of someone you've met before. Often the solution to a problem comes to you in much the same way you eventually recall the name.
