One factor that has been left out -- is the idea, picture, smell, whatever it is that drives the seeker. The primary mover of the seeker human. (We have lots of dogs, and they usually get a scent of something, then go looking for it. Our customers are primarily seeker types. I discovered early on, they came to us with a picture or sensory combination, in their mind, and my job was to anticipate what those pictures/combination of senses, will be, and design products for them. I remember one customer saying to me "I knew something better had to be out there." (She was an astronomer, so I guess "seeker" describes her well !) I'm a seeker type too, and I don't like the finding to be too easy.
