Okay, so for whatever reason you can't get your hands on a book.
Maybe you're stranded waiting for someone to come fix your car, or the library just closed and you don't have the budget to buy a book, or some other unfortunte combination of circumstnces. I get it, it happens.
Here are some other ideas:
Call a friend to catch up.
Do some yoga or stretch.
Make a list of things for which you are grateful.
Plan for how to get a book so you're not stuck in this situation again.
