Do you have a memory of a time when you were super close-minded? Let’s be real: If you’re like most of us, you probably have a dozen of them. There’s nothing funnier than seeing a 10-year-old think so black and white about a subject, all the while knowing she will better understand the shades of gray later on. As we get older, we learn being insular just isn’t cool. You close yourself off to getting to know some really astounding people and gaining some marvelous knowledge. Today, embrace open-mindedness. Give someone new a chance, like that over-the-top server at your favorite lunch spot or your relative known for her questionable social-media opinions.
