Burnout remedy?

I saw this post by Tony Campolo today and I will be putting this book on my Amazon religion wish list (one of 5 wish lists I have at Amazon, I think I'll add links to them in the side bar), for anyone who wants to get it for me for my birthday. :) I have not been as successful as I'd like recently in working on my own spiritual practices, but this sounds like something I can/should try.
