There's no doubt about it that John Cleese is a genius when it comes to comedy but his genius-ness (is that even a word?) doesn't stop there. What follows is one of my favourite videos from him. The highlight of which is this enlightening little piece of wisdom:

To know how good you are at something requires the same skills as it does to be good at those things. Which means if you're absolutely hopeless at something, you lack exactly the skills that you need to know that you're absolutely hopeless at it. And this is a profound discovery - that most people who have absolutely no idea what they're doing, have absolutely no idea that they have no idea what they're doing.

It explains a great deal of life.

It also explains why so many people in charge of so many organisations have no idea what they're doing, they have a terrible blind spot.
