The “what if” of the past can drive a person crazy. What if I did this? What if I didn’t do this? Could it have changed anything or made things better? Guilt, regrets, helplessness, frustration, etc. mingle in a never ending negative loop pulling the person down the hole of the permanent past.
On the other hand, the “what if” of the future is full of potential. It is the “what if” possibilities, the options, the choices, life, the thoughts that generate hope, enthusiasm, and a path that leads to positive ends.
