I'm currently reading the book Ten Years Later, by Hoda Kotb. It is a non-fiction collection of stories regarding six different people "who faced adversity and transformed their lives" (book cover description). As an example, one story is about a woman who lost well over 300 pounds and was nearly killed in an abusive relationship, and how she is doing after ten years (I struggle to not say how she is doing in my blog post - you'll have to read it to find out). I've read through the first story so far (the one of the woman above), and look forward to reading more!
Amazon's description includes the following: "Ten Years Later is a firsthand testament to the enduring power of the human spirit. Through inspirational life stories, Hoda shows how adversity can unleash our best qualities: resilience, perseverance, gratitude, empathy, and creativity. This book will inspire you to believe in the future, no matter how dark the present, and tap into the ability to reach your highest potential."
UPDATE: This book is great for people who can't, or don't want to, sit and read an entire book in one or two sittings. Each person's story is basically it's own "chapter," so you can read a story at a time. Also, the stories vary in length, too, so you can choose to read longer or shorter stories depending on how much time you have. Example - the first story is 35 pages, the second story is 63 pages, and the third story is just 22 pages long. Nice.
UPDATE #2 (2/19/2013)
Ok, I'm still reading this book! I've only been able to read a little bit at a time. I do hope to finish in the next week. :)
