"You do not have a soul; you are a soul. You have a body." C.S.Lewis
Did that wake you up?
You are a soul, made for eternity, that just happens to have a body right now, temporarily. The body perishes; the soul is immortal.
When you look at another person, don't look at them as a body; look at them as a soul.
Try living with this thought in your mind for a while. It should give you a different perspective on things.
