Anytime you see a constrained market, where consumption is limited to those who have special skills or are wealthy, that signals an opportunity for innovation.

It takes a great deal of humility to recognize you have made a wrong turn on the road to successful innovation, but better to stop and try a radically different approach then to continue down the wrong route for too long.

Of course, it is worth it to take the time to think carefully through your assumptions, and ensure you at least have hypotheses around how you will create value. But use the analysis as a way to focus attention on the most critical assumptions, rather than spend a ton of time massaging the numbers.

Everyone knows innovation involves developing unique understanding of a market, thinking expansively to develop a solution, and then finding a way to test rigorously and adapt quickly.

Make sure that you take the time to think about how other companies might respond to your idea, both those companies already in the market you plan to target as well as others that might imagine targeting that market.

Now, I worry a bit about the TEDification of the world where style trumps substance, so hopefully you have a good blend of both!
