The old what if game, I hate what if. What if a frog had wings - it's butt would not bump the ground every time it jumped. There are just so many variables in everything that every one does much less a team. If I had left home 1 minuite earlier or later I would not have got in the wreck or I would not have got that ticket. What if I had taken better care of myself 50 years ago I would not had as many aches as I do now. It goes on and on for ever.
Yesterday is history and can not be changed, tomorrow is a mystery, today is a present so use it wisely.
