Now take those numbers and project a straight line out to 100,000 times that investment ($400k) while removing the word "coffee". Is there some level of consistency in the motiviators?
I guess...yes? This is clearly in your wheel house, so I'm trying to follow out the logic. My guess is that whether the coffee/audio analogy can be extrapolated in this way would depend on empirical psychological factors which someone could study. It sounds like commonsense to me, but the devil would be in the details! ;-)
