" I believe that getting stuck is often an essential part of the creative process. And when we are stuck—if we have managed to escape the heave and rush of the world, if we have managed to secure solitude and quiet and space without time—then our minds can roam and explore and invent in unfettered freedom. But too often we dread being stuck. Especially our students and young people. We believe that if we are stuck we are failed. On the contrary, we should welcome getting stuck. We should embrace getting stuck. That's when discovery begins. "

― Alan Lightman , In Praise of Wasting Time
