It applies on every aspect of life like if you love someone but that person can't be with you for some reason, then don't let them say No to or Reject you. Instead
Leave them before you are left.
Why to run after someone who choose their reasons on you? Its a beautiful life.
Many people will come into our lives, some will stay and some will teach lessons
Never take love or anything for granted. You are as precious as others are who reject you. So, have the power to say No to people.
