Stop comparing your life to other people

Some of us strongly believe that other people that are not even in a relationship and that never had a relationship at all in their life have a better deal and a better life than us. We start taking our partner for granted because you look away from what we have in our life and believe the grass is greener other there for others.
We are not grateful for what we have and start to dream away to get a better deal.I am saying, there are not better thing out there as you always find something better, But we cannot be satisfied with our life and in ourself to always chase what we don't have and don't possess.
