One of the most effective ways to come up with new Insights and ideas is to switch medium.
No matter what challenge you are facing, try thinking of it and expressing your thoughts using different mediums. Try drawing something, or writing a short story. Try building a Lego model or take some photographs outdoor. The more diverse the media you use is, the more surprising and insightful the results are.
Try also mediums you are not accustomed to. It doesn’t matter if you feel you can’t draw. Do it anyway! The goal is not to create a masterpiece but only to activate connections in your mind which you don’t often use.
