The problem with the great idea is that it concentrates the mind on the idea itself. This is fine as far as it goes. But unless the idea is executed efficiently and with panache and originality, then it doesn’t matter how great the idea is, the enterprise will fail. Ideas are certainly of immense importance, but I have seen so many people attempting to create a start-up company become obsessed with proving that their idea is ‘right’ rather than obsessed with making money. And I have watched them wasting years doing it.
