At school any spontaneous act was likely to get me into trouble. I learned never to act on impulse, and that whatever came into my mind first should be rejected in favour of better ideas. I learned that my imagination Wasn’t ‘good’ enough. I learned that the first idea was unsatisfactory because it was (1) psychotic; (2) obscene; (3) unoriginal. The truth is that the best ideas are often psychotic, obscene and unoriginal.
