Like drawing a straight line – you draw a straight line and it's crooked and you draw another straight line on top of it and it's crooked a different way and then you draw another one and eventually you have a very rich thing on your hands which is not a straight line. If you can do that the it seems to me you are doing more than most people. The thing is, it is very difficult to know oneself whether one is doing that or not, whether you mean what you do; and there is the other problem of the way you do it and whether sometimes you do more than you mean or you do less than you mean. It's very good if you can establish a language where it's clear that that is what you are doing – that you do what you mean to do.
