Just jumping in here to say that I started reading that book on willpower that I mentioned in passing a couple of days ago and it's really, really interesting. I am only on chapter two and I'm riveted.
Here's a link to a NYT review of the book, Willpower: Rediscovering the Greatest Human Strength by Roy Baumeister and John Tierney.
I will be writing about this one when I finish it.
I made a resolution last year to wait for new books to come from the library rather than making impulse purchases, but this one I couldn't stand waiting for any longer and after reading the review finally hit the "buy now" button for the Kindle edition. I think there's probably some irony there, but I don't want to look too hard at it.
