You know the paper mazes on every child activity placemat and cereal box? And also the ones in big books of them made of tiny lines barely big enough to fit a pencil point?
The little ones are easy, you can usually see the way to the end by sight, without ever putting pen to paper. They practically solve themselves. The big ones seem like they’ll take a week, testing out pathways, backtracking, trying a new opening.
The metaphor speaks for itself. The only thing is that you don’t necessarily know which kind you’re working through when you start. You just have to trust that there really is an end, somewhere, and start working it.
