Do you think of yourself as a generalist or a specialist? This week’s Friday Memo book selection is Range by David Epstein, and it completely reframes the way we think about success, specialization, and nonlinear careers. The part I can’t stop thinking about: we glorify the Tiger Woods story, the child prodigy who specialized early. But Epstein argues that Roger Federer’s path, trying multiple sports before committing to tennis, may actually be the better model for most of us. If your path has ever felt scattered, delayed, or hard to explain, this book makes the case that your range might be your advantage. Let me know what you think.
