Fill what's empty

...empty what's full. Scratch where it itches.

This is a pieceof life advice I gave myself sometime ago. I don't remember where I found this out, but I wrote it down on a tiny scrap of paper in my room at my parent's house.

Then as I moved out to live elsewhere, I found this tiny scrap of paper, and I like it's philosophy.

It's simple, can apply to anything, and means I can scratch myself if I'm itchy.
