Songs really are like a form of time travel because they really have moved forward in a bubble. Everyone who's connected with it, the studio's gone, the musicians are gone, and the only thing that's left is this recording which was only about a three-minute period maybe 70 years ago.
Keep these concepts in mind: You've failed many times, although you don't remember. You fell down the first time you tried to walk. You almost drowned the first time you tried to swim. Don't worry about failure. My suggestion to each of you: Worry about the chances you miss when you don't even try.
