Many years ago, I took a weekend seminar on innovation and bringing your ideas to market. The teacher of the class shared something that I have never forgotten. He said that, when you think you’ve come up with a truly new and innovative idea, and you share it with your confidants, pay attention to how quickly and easily they embrace it. If they immediately get it, and get excited about it, you may obviously be on to something, but likely, so may a number of other people. Their immediate and enthusiastic reaction means that the cultural and market vectors may have already firmly converged on that very spot that you just identified. On the other hand, if you tell them and they don’t get it right away–but after thinking about it, or you do more explaining – they get it then (i.e. a slow uptake rather than an immediate eureka!), you may be ahead of the curve. When I first heard this, some 30 years ago, the tip itself worked in exactly the way that it describes. It didn’t have tremendous resonance to me in the moment. But over the years, it has been borne out so many times, I now count it as true wisdom.
