No Radio

During the week, I have a fairly long commute to and from work.  Sometimes I listen to a book on cd.  Sometimes I listen to my ipod.  Most of the time I listen to the radio.  I am usually tuned into 89.3 The Current because the DJ's are great and the music isn't so bad, either.  
Tonight I tried the radio, but I had to turn it off. It wasn't because the music sucked, or because I was on the phone while driving.  
It was because I had a lot of thinking to do.  My mind was preoccupied with questions about my life, my future, and possible decisions to make.  The message that kept coming up the most was that I have to find my joy.  What brings me joy?  What makes me feel happy and inspired?  
Sometimes that seems like an easy question to answer, other times, it's a mystery.  
Maybe I'll have to make the commute in silence all week long, just to see if my inner, wise voice will make itself loud and clear for me to hear.
