Val - tongue-in-cheek, I'm sure - asked for suggestions of books on willpower to help her avoid the baked goods we've been talking about this week.
In case it's a topic in which there's some interest, I thought I'd give it a post of its own and say that while I'm no expert here, the one book that springs to mind is Gretchen Rubin's latest, Better Than Before: What I Learned About Making and Breaking Habits to Sleep More, Quit Sugar, Procrastinate Less, and Generally Build a Happier Life. I haven't read it, but I have read and enjoyed her bestselling The Happiness Project: Or, Why I Spent a Year Trying to Sing in the Morning, Clean My Closets, Fight Right, Read Aristotle, and Generally Have More Fun, and having followed Gretchen's blog for years and tuned in to her podcast, I know a certain amount about the substance of the habits book.
The gist of it is that if you can identify which personality type or 'tendency' you are - upholder, obliger, questioner, or rebel - then you will be better able to adopt particular strategies which will help you establish good habits and avoid the loopholes which can make it harder to break 'bad' habits. Simple!
If you can recommend a book on willpower, habit-change, personal development generally, do tell us in the comments.
