Worry.

Today was a very interesting, intense day full of surprises and laughter and tears and shock and dismay.

This song just came up on Pandora and I really like the last few lines:

Karen O. and the Kids, "Worried Shoes"

One day I looked around and I found the sun shining down
And I took off my worried shoes
And the feet broke free
I didn’t need to wear
Then I knew the difference between worrying and caring
‘Cause I’ve got a lot of walking to do
And I don’t want to wear
My worried shoes

* Don't carry around worry, fear or anxiety. They are the thieves of peace.
