"Our lives are not determined by what happened to us, but how we react to what happens; not by what life brings to us, but by the attitude we bring to life. A positive attitude causes a chain reaction of positive thoughts, events and outcomes. It is a catalyst - a spark that creates extraordinary results."  --- Anonymous.
