Work ethic is a mindset, not a lifestyle.
It is not about how many hours one sits in an office, or how late into the night one works. It is not about how many meetings or emails or deals you get through.
It is about obsession. World class work ethic is about when you can’t help but think about your craft: what to do next, how to improve, how to chase excellence. You think about it all the time. It can be anxiety inducing at times, but always energizing. It’s hard to fake.
Every successful person in a field with power law outcomes has had it.
