But in a fast-changing world, what if the really crucial skill is knowing when to stick at something and when to change track and walk away? Quit makes the under-appreciated case for quitting and also shows you how to get really good at it. Drawing on stories from elite athletes to Everest climbers, comedians to musicians, Annie Duke (who left a successful poker career) explains why learning to quit well is often crucial to success.

She provides clear strategies for working out when to cut your losses from a business product that isn't working, a relationship turned toxic, or a career that won't take you where you want to go. You'll learn how to spot the blocks to good quitting behaviour -- escalation commitment, desire for certainty and the status quo bias -- and also how to use tools like quitting contracts, flexible goal-setting and premortems to help you quit cleanly and confidently.

Whether you're facing a make-or-break business decision, a life-altering personal choice or simply wanting to take more control of your life, Quit provides a toolkit for change to help you make the best next move.
