I will go to great lengths to avoid running. It’s not my thing. So when my husband offered me a copy of Limitless that he’d picked up after listening to Author Justin Levine speak, I was less than enthusiastic. To my delighted surprise, I was hooked after the first page and ended up reading it straight through. The book is an inspirational look at obsession and the lengths someone will go through to test one’s own potential and limits. While I am not a runner, I do understand that inner drive that makes a person obsess over conquering something. Levine’s book comes the closest in describing why. Why? When others ask why do “that”? Why climb Mt. Everest? Why start your own business? Why put your body through torture? Why do you get out of your comfort zone? I’m still not sure I have the answers to those questions, but Levine explains well why he pushed his boundaries in “Limitless.”
