I like this line of thought. I’d add that another dodgy idea is stereotyping. You could make the mistake of saying customers are other-than-us; or you could think the customers-are-always-right. Nah. Just watch the TV programme Airline; some of the customers on that show are just as outrageous as the dodgy plumbers they like to nail on consumer TV shows.
Instead of fearing absurdity, it’s possible to embrace it as a way of increasing creative confidence
