I am often asked about where I get my ideas, and I always first shrug, then say that I get them from everything that is around me. John Cleese of Monty Python fame gives an excellent explanation in the video below about what one needs to be creative. He is absolutely correct. Remember that 365-day project of mine, in which I had to make a piece of art each day? One of the important parts of being able to do that was to establish a two-hour time period for making that piece. Cleese gives himself an hour-and-a-half. Another was to let every absurb idea be examined. And so on. The video is long—a bit over half an hour—and has Norwegian (I think) subtitles, but it is all worthwhile. And, you don't actually have to watch it; you can just listen.
