One thing a lyricist must learn is not to fall in love with his own lines. Once you learn that, you can walk away from the lyric and look at it with a reasonable degree of objectivity.
“I'm an old-school, embarrassing Joni Mitchell fan. Her music made a hook in my soul and hasn't let go for all these years. I even sing her songs as lullabies to my kids.”
“Why do people talk of the horrors of old age? It's great. I feel like a fine old car with the parts gradually wearing out, but I'm not complaining,... Those who find growing old terrible are people who haven't done what they wanted with their lives.”
