Many are fighting a battle you may never know anything about. Keep that in mind before you pass judgment on others. 

Don't be the person who lives in the past unable to let go...one day you will look back at what you lost because you could not make room for a better future. Forgive others not for their sake but for your own peace of mind.  I know I am not perfect, I am sure I made mistakes and I have to live with them but I know that I need to value peace over conflict. The world becomes a lonely place when we hold onto hate and shut everyone else out.

Life does not promise that there will be a tommorrow.
