Quit: The Power of Knowing When to Walk Away

Why I recommend it

I recommend this practical case for treating quitting as a decision skill rather than a failure of character. Duke explains why sunk costs, identity, uncertainty, and the desire to appear consistent keep people committed long after the evidence has changed.

What it changed in my thinking

Persistence is only useful when the goal still deserves the resources it consumes. Defining exit criteria before emotion and investment escalate can make stopping both clearer and more honest.

Who it’s useful for

Leaders, founders, investors, career changers, and anyone deciding whether a difficult commitment needs more patience or a deliberate ending.

A tension

Quitting sooner is not automatically wiser. Decisions still require judgment about recoverable setbacks, long feedback cycles, obligations to other people, and the cost of abandoning something that has not had a fair chance.
