For some mid-day inspiration, check out this sneak peak video from an upcoming ABC primetime special (“Adventures of an Incurable Optimist” airs Tuesday, May 7) from actor Michael J. Fox, who has battled Parkinson’s Disease since he was 29 years old. 

Fox traveled the country and the world in search of the meaning of optimism–as one person he met told him, “You can turn any situation into a positive–maybe not for you, but for someone.”

What does optimism mean to you?
