I read a fun article in Real Simple today - Gail Blanke "Find Your Song (and sing it)."
"I wondered where you get that kind of conviction, that you're exactly the right person to take the room, get the part, knock 'em dead? I bet it's from the music. ... We all need a song."
She believes that everyone needs a theme song, a pep-me-up, for those times when you're about to do something that makes you nervous. Or she counseled a 40 year old exec whose boss had told him to work on his communication skills: he recalled when he used to play soccer, he would sing "My Sharona" in his head on the way onto the pitch, to get in his super-star mode; she told him--well you have to do the same thing before you go meet a client! "Roger came out of himself; he became a motivator. He energized his clients, and they loved it."
I used to have my I-am-nervous theme song, but I'd forgotten til I read this article. I think it started in grade 11 when I was leaving my driving lesson. Going to my driving lessons made me queasy, and leaving them, I felt like an idiot. And I recall walking down St. John's singing to myself "I Have Confidence" from The Sound of Music.
After that, I used to sing it all the time in nervous situations. It's a great song because it's long, with lots of lyrics, so remembering it all keeps my brain occupied. And I love the way it starts with Nerves, builds into Confidence, builds into Bursting Confidence, has one last moment of Nerves ("oh help!") and then ends on one last blustery I'm-gonna-fake-it-if-it-kills-me note. I mustn't forget this again... it will come in handy for teaching.
"Somehow I will impress them
I will be firm but kind
And all those children
--Heaven bless them--
they will look up to me
And mind me!"
I guess you could have a few sub-songs for specific situations. Blanke has a client who chose a specific song for dating, after her marriage ended. When I'm on my way to an exam I sing "funky fresh dressed to impress - ready to party" by Missy Elliott.
If you have a power-song, you should Commentify me. If not... well, you should get one.
