I reckon the most important muscle in the world is the imagination, and it must be exercised constantly in order to stay in tip top shape. Nothing good can be done without first imagining it. For instance, an escapee could never escape from prison without first of all imagining exactly how they are going to do it. All to often we might find ourselves kicking back and absorbing the world and letting our imagination get weak. Can you imagine a kinder world and how we get there? Can you imagine a better way to live? Can you imagine a colour that hasn’t been seen yet? Keep a list of all the things you imagine in your journal.
