Life as we know it

Today all is calm in your life.  Tomorrow it is turned upside down.  We just don't know when it will happen.  Then you have people who must fight you every step of the way and won't stop.  I'm sure their day will come too.  If you are carrying the world on your shoulders you don't need someone to come along and upset the world.  Why can't people just stop.  No, push someone over the edge instead.  Thanks!
