Rodney Crowell on failure, knowing when it's done, and vision quests.

Rodney Crowell is the definition of a legendary songwriter - he has multiple Grammys, 15 #1 singles (5 from 1 record), and everyone from Emmylou Harris to Bob Seger, Waylon Jennings, and George Strait have recorded his songs. He is also incredibly wise, and generous with his insights - we talk with him about failures, using vision quests to reset and recenter, defining success, and how Guy Clark taught him when to know a song is done.
