I was turned onto this book by Dave Ramsey, who recommends it on his website.
It's the true story of a young college graduate who sets a goal after 365 days to go from homeless with only $25 in his pocket and the clothes on his back to having $2500 in savings, having a roof over his head and a car to drive. It's an entertaining story, told from his perspective.
It made me appreciate what I have and reminded me to stop whining and complaining when I begin to think about what I don't have. The book restored my "make it happen" attitude. It reminded me to get back to the basics, set goals, and do everything I can to achieve them. I highly recommend it. I won't ruin the ending for you.
