John Lennon talks about Instant Karma, that should apply to everything in life. If you are nice to people they will be nice to you.
If you are nice to a client, the client will be nice to you. If you are nice to to the guy next to you in traffic, he will be nice to you.
Instant Karma’s gonna get you
Gonna knock you right on the head
You better get yourself together
Pretty soon you’re gonna be dead
