The royal courts used to employ jesters to ensure their thinking didn’t just succumb to the ‘yes men’. Their role was to be purposefully provocative to ensure decisions were appreciated from other perspectives and embarrassments were averted.
So play the role of the court jester by laughing at your ideas and kick yourself out of your bad thinking habits. You will open up your playful side ready to be more creative in your thinking. If you subsequently find yourself trapped in your thinking, you will be ready to laugh at yourself once more and free your mind.
