I still get goosebumps when I think about it: the moment I had the searing personal realization that my assumptions about how the world works don’t necessarily hold true for everyone.

The road to that realization began nearly three years ago, with the fatal police shooting of an African-American man in the parking lot of an apartment complex near one of my company’s locations in Charlotte, North Carolina. Coming amid a rash of other high-profile deaths of African-Americans at the hands of police around the country, the incident sparked immediate protest that turned to rioting and violence followed by several days of high tension throughout the city.
