John Cleese:
"...in order to know how good you are at something, it requires almost exactly the same skills and aptitude as it does to be good at that thing in the first place. In other words, if you’re a really good tennis player or mathematician then you know how to tell how good you are. But it also means if you’re absolutely no good at something then you lack exactly the skills to realize your idiocy."
Oh dear! I'm afraid that's true...
