By far the BEST autobiography out. If you think you've read them all, then take a look at Bear Grylls' new book. The passion, determination, sweat and tears he puts into everything he is set on achieving in his life is astonishing! From a Broken back to scaling Mt. Everest and all it's glory. This is one motivational book that lead myself to lead a healthier lifestyle. I owe it all to this man and his words.
