If you purchase a Mercedes or Lexus what do you expect? If you are in a job and always looking for another one, what are you looking for? If you are in a relationship or marriage and always thinking it should be a different way, how should it be different? These are all internal sales messages you are doing to yourself. YES, you sell everyday - externally and internally!
Your internal expectations of a product, service, person or experience sell or unsell you. It is up to you whether the grass is greener on the other side or if you are willing to water and care for the grass you have.
