There are things you do every day, things you don’t even see anymore. Pure habit. The best way to challenge your assumptions is to watch someone else do something just as mundane and see how differently they do it.

You can take this to literally be about dishwashers, but the especially cunning among you will notice that you can just as easily apply it to wildly different domains as well.
Like washing machines.
