Annie Duke explains why we often quit much later than we should and gives us strategies for quitting at the right time.

In 1998, three climbers turned around three hours from peaking Everest, sticking to the established turnaround time for returning to base camp.

Those climbers survived, while two of their companions ignored the turnaround time to summit the mountain and died on the descent.

Even in situations that aren't life or death, quitting can be a better option than blind perseverance.

Annie Duke is a best-selling author, corporate speaker, decision-making consultant, and former professional poker player.

In Quit, Duke explores the cognitive biases that prevent us from quitting at the right time, citing real-world examples and providing strategies to improve our decision-making.
