I bought a guitar!

I've been feeling the need to have musical expression in my life again (now that I'm not working at a flute company anymore), so I bought a guitar. I got it from a friend for $90. It's a Yamaha, steel string, folk (6 string), and it sounds quite nice. I was so excited to go to the music store on Saturday and buy a few books. I got a beginning technique book, easy Beatles songs, and pop tunes made easy. I even discovered that there's an incredible guitar store down the street from me (I can literally walk there). They give beginner group lessons for 10 weeks at a reasonable price, so I'm going to sign up. Maybe I was meant to be a rock star. All I need now is a suitable rock star name. Suggestions welcome.
