When we feel guilty about taking time to do what WE want to do.

"If you like to make things out of wood, or sew, or dance, or style people's hair, or dream up stories and act them out, or play the trumpet, or jump rope, or whatever you really love to do, and you love that in front of your children, that's going to be a far more important gift than anything you could ever give them wrapped up in a box with ribbons.  And what's more:  The last thing in the world you have to be is perfect at it.   It's the spirit that gives that kind of gift its wings."

--Mr. Rogers
