It was a perfect summer night for an outdoor concert at Jones Beach. As Rod Stewart expressed during the concert, it was much preferred to the rain that poured on one of his last concerts at the venue.

I usually walk away from a concert with an ear worm--that lingering, repeating lyric that won't go away.

"I wish that I knew what I know now, when I was younger...." (from Ooh la la)

As the lyrics persisted in my mind, I wondered:

Do I really wish that I knew then what I know now?

If I did, What would I have done with it?
