Recently, I was listening to one of Hal Elrod's pod casts in which he suggested starting a 30 Day Challenge. For those of you who have never heard of Hal Elrod, he's the author of The Miracle Morning. It's a life changing book. I would strongly recommend watching his pod casts & reading his books. He suggested taking on one new challenge every 30 days. I thought this was a fantastic idea. What's your favorite 30 Day Challenge?
