Willie Nelson plays "the angel's advocate" because he shows us all that although it's far easier to be negative... it’s by far more productive to be a positive person. I don't care if you love or loathe country music... Willie Nelson is a positive thinker, a positive talker, a positive doer and an all-around positive guy who has a bunch of friends from all over the world. "W" knows that ya' can’t afford no negative thoughts.
