It was my third day on the job at a hot Silicon Valley start-up in early 2013. I was twice the age of the dozen engineers in the room. I'd been brought in to the company because I was a seasoned expert in my field, but in this particular room, I felt like a newbie amongst the tech geniuses. I was listening to them talk and thinking that the best thing I could do was be invisible. And then suddenly, the 25-year-old wizard leading the meeting stared at me and asked, "If you shipped a feature and no one used it, did it really ship?" "Ship a feature"? In that moment, Chip knew he was in deep ship. I had no idea what he was talking about. I just sat there awkwardly, and mercifully, he moved on to someone else. I slid down in my chair, and I couldn't wait for that meeting to end.
