You can choose heads or tails but once you’ve made your choice it will stay with you until the next flip. If one takes the side of the negative then it’s very hard to see the light on the other side while those who choice the positive let the darkness fade into the distance. Seeing the good in individuals that have their cup 1/2 empty is very difficult but it allows you to taste the part which is full. A traumatic event can have you stuck on one side unless you decide to flip it and see what good can come of it. On the other hand one can’t lead a life of naivety because eventually it will lead the other way around so make sure you keep flipping to see it all along the way.
