Blake Shelton lost his father last year.  Richard Shelton died after a long battle with a lung disease.  But, Blake was able to get some sound advice from his father after the death.

Blake moved to Nashville when he was a teenager.  A few weeks after he left home, Blake's dad sent him a letter.  Blake recalls to Men's Journal, "The first couple lines said, 'Hey, I didn't get a chance to tell you some things that I wanted to tell you about entering the world,' and as soon as I read that, I folded it back up."

The Sheltons never had a bad relationship.  But, as Blake says, "I was 17. I didn't want to be told what to do."

Blake eventually lost the letter.  But, after going through some stuff after his dad died, Blake found the letter in a tin popcorn can.  So, he finally read the letter.  It was full of good advice like, "How to get respect, how to look people in the eye, and how to shake their hand.  Basically, how to be a man in the world."

Blake Shelton says, "It was like I was having a conversation with him I never had."
