I like to spot paradoxes or at least ambivalences in my thinking. One that cropped up today was quite significant because if I knew that unless I wrote it down it would vaporise and float away. As I was just then thinking about this blog posting, it seemed a great starting point. Sadly, I failed to implement a key step in my current cognitive strategy, namely that when you have an idea you must write it down immediately and not leave it until later in the evening!
