One of the basic rules of the universe is that nothing’s perfect. Perfection simply doesn’t exist. The cosmos had taken its first step toward the beautiful place it is today all thanks to irregularity, imperfections and luck of order. So the next time someone complains that you have made a mistake, tell him that may be a good thing. Because without imperfection, neither you nor I would exist.
