What's your life theme song?

There are times when I wonder what my life theme song would be. Sometimes I think about it as the song of the day...theme of the day or week or month. And then there's the "life" theme song...the one I strive towards...the one I also fail at and then get to learn more life lessons.
So, this is one of my top three Life theme songs.

Be fearless,
Josie
