But if we leave them and start thinking about the subject without any limitations we end up with very good ideas. This happens many times to many of us.
Sometimes when we are trying to find out a solution to a problem and we are not able to get an answer, somebody who is no way related to the problem may give you a clue which will help you in solving the problem.
So as said by the author, don't go through highways to reach the distance. But try a new route so that you will be a creator of new route to that destination.
