One thing I used to do when I was little is READ, READ, READ!
It's a totally cheap vacation. It's an escape--and we all need to do that from time to time.
When I was little, I used to go to the library and stand in awe of the volumes and volumes of books. My goal was to read every book in the library, and then I thought I would know everything in the entire world.
I've gotten away from reading lately, and I need to go back to it! One of my besties sent me the link above last week, and it was just what I needed.
