Although recently posted on Youtube, this John Cleese speech on creativity was given before his hair turned gray and thin. Like everything Cleese does, humor abounds, but between the jokes is some good advice. There is some especially good advice for writers.
Here’s a Snippet of him blending humor with wisdom:
“The only thing from the research I can tell you about how to be creative is the sort of childhood you should have had, which is of limited help to you at this point in your life.”
He actually goes on to give some great tips on being creative in adulthood. Writers should listen carefully.
