You forgot the filter. As we grow older we lose our filter. We just say whatever comes to mind and we do not worry about others feelings or being politically correct. There may be times where the truth needs to be said and it cant be filtered. Just because the thought is in our mind does not mean it needs to be said .It all boils down to our hearts and minds. If we focus on only the negative then the only thing that comes out of us is going to be negative. We must try to find the good in people and find positive things to say. As we grow older hopefully we have a lot of wisdom that we can impart to the younger generation. If all we are doing is being negative they wont hang around long enough to hear some of your lessons learned.
