“The advice to trust the numbers isn’t motivated by geekery; it’s motivated by humility. We can’t lose sight of what the numbers represent: A lot of people like us—people full of passion for their opportunities—spent their time trying something very similar to what we’re contemplating. To ignore their experience isn’t brave and romantic—“I’m not going to let some analysis stand in the way of doing what I believe.” Rather, it’s egotistical. It’s saying, We set ourselves apart from everyone else. We’re different. We’re better.”
