Here are some odds & ends I have observed in creative-expert-genius types:
Direction of motivation: creatives move toward what they want in all areas of their life while clods move away from what they don't want.
Time orientation: creatives look forward to completion. Clods look backward at how they have been unable to do it and assume future is also failure.
Memory management: creatives look toward constructed imagery combining new with old to create. Clods rely almost exclusively on eidetic imagery of past for repeat type solutions.
Time distortion: creatives get in a groove and time goes zip. Clods drag out time
Perceptual positions: creatives use a 1-2-3 way of processing info where 1 represents self, 2 is other and 3 is observer. They move in/out of these various frames of reference to gather info not available to any single position. Clods are rarely aware of anything but position 1.
Perceptual roles of dreamer-critic-realist. Creatives remain in dreamer mode for decades and use critic role to make dream better and realist mode as final preparation for making dream come true. Clods kill dream almost immediately by allowing critic/realist into show before dream develops enough to have a life of it's own.
Exagerrated sense of worth/potential. Creatives believe they are more capable than their peers or family think. Clods accept limiting beliefs of those around them as accurate.
