Ben Bajarin:

Creating something new or unique is not terribly difficult. I’ve got great ideas for all kinds of unique products that no one wants but me. Creating something new, unique, different, and innovative that garners mass market success is EXTREMELY difficult and more interestingly EXTREMELY rare. The fundamental challenge and to a degree fear around innovation is that you create something the market does not want. This at its core is the reason why it is easier to follow the leader than blaze a new trail.
