We were talking about why some roles don't work out — why people get fired or quit quickly or whatever — and Don said, “At some point in your career — when you know what you're exceptional at — if things don't work out, it's not about you, it's about fit.” I recently wrote about this a bit in my post about Joy: the idea that finding a role has two sides to the equation — the jobs you want and the jobs that want you. Fit is about where (and whether) those two sides meet.
