It's a strange feeling, that sudden realisation that you are, quite frankly, small time. To see someone do something that you thought you did well better than you had even realised it could be done, moving the ceiling of what you thought was possible. It's like being told you are an eight, an eight out of ten, you assume, only to discover that in fact the highest score is in fact 100.
I think the trick is to respond with 'I can be 100? awesome!' but it can be hard, especially when you are sitting around listening to the Flecktones or reading Joseph Heller.
