Today, October 21, 2015, is officially the hallowed “future” day that Marty McFly and Doc Brown visited from the 1980s in Back to the Future II. Like most of us who grew up on the Back to the Future franchise, we eagerly awaited the day when we too would have a pink hoverboard, self-tying shoes, and highly questionable fashion sense. Well, kids, that day is finally here, and Doc Brown — inventor of the time machine that made this all possible — has a little wisdom from the past to share with us all in the future. Great Scott!
