My most useful life hack is Libby + kindle. On Libby, put a few books you'd like to read on hold. Once they become start become available, suspend them until you have a couple books built up. Then unsuspend, add to kindle, open the books so they download, and turn your kindle on airplane mode and return the books. Read them all at your leisure! Start the process over! Win the lottery every time you load up the kindle!
