The good news is that if even one person is brave enough to defy the majority, we are emboldened. We’re not alone anymore. We’re not crazy. And we feel we can call red “red.” In short, courage is contagious. From historic protests to everyday acts, from the civil rights movement to an employee asking a tough question, this is the lesson we’ve learned: It is hard to be courageous, but it’s easier when you’ve practiced, and when you stand up, others will join you.
