The best innovations arise by following the path of most resistance, not least resistance. As Amnon Levav at SIT writes, "In nature, water cascading down a mountain follows the path of least resistance - the easiest route to arrive at its final destination. In thinking, too, our minds tend to take the path of least resistance - those avenues that are familiar to us. So doing, it is difficult to arrive at ideas that are new to us or to our competitors."
