"Beyond the blue horizon— Tom McMahon, from his must-read post "What I Have Learned in 15 Years". (Thanks to reader Joseph for the link.)
Waits a beautiful day
Goodbye to things that bore me
Joy is waiting for me
"I see a new horizon
My life has only begun
Beyond the blue horizon
Lies a rising sun
"Memorize this song. It's simple enough that when you're in real trouble, you'll still be able to remember it. If you're a Christian, you can substitute 'Rising Son' for 'rising sun' and nobody will know the difference when you sing it."
