An introduction to “life hacking,” Urawaza is a Japanese term referring to unlikely solutions to common problems – like buffing your fingernails with a receipt.

One of the most satisfying things about this book comes from its light-duty lateral thinking – even if you don’t get around to employing one of these solutions, you’ve already started to think about the situation in a different way. And what’s more basically satisfying than that?
