Impose a limitation to spark creativity

Artist Phil Hansen "embraced the shake". He embraced a physically limiting shake in his hand to go on and create some magnificent work. Embracing our limitations can enhance new thinking and spark ideas. Alternatively, imposing a limitation or constraint on a familiar challenge can force us to take a new path and come to a new solution we would never have thought of.
