There are many words to describe Michael J. Fox: Star. Husband. Father. Activist. But one word encapsulates everything he stands for, everything he's accomplished: Optimist. Struck with Parkinson's at the height of his fame, Fox has taken what some might consider cause for depression and turned it into a beacon of hope for millions. In Always Looking Up, he writes about the personal philosophy that carried him through his darkest hours, and speaks with others who have emerged from difficult periods with optimism to spare. With humor and wit, Fox shows how he became a happier, more satisfied person by recognizing the gifts of everyday life.
