Concept
Opportunity Cost
Opportunity cost is the value of the best alternative given up when we make a choice. In Quit, Annie Duke treats it as the cost most often left out of the decision to keep going: sticking with something is never free.
Opportunity cost is one of the basic ideas of economics, yet it is routinely forgotten in decisions to stay. When we weigh whether to continue, we usually compare continuing with stopping, and stopping looks like nothing. The real alternative is whatever else the same time, money and attention could do. Duke argues that this omission keeps us too long, especially in situations that are acceptable rather than bad: a failing project eventually forces a decision, while a merely adequate one can run for years without being questioned. The remedy is to make the alternatives visible: knowing what else is available, exploring a little alongside the main commitment, and holding a realistic backup. The question then changes from 'is this bad enough to quit?' to 'is this the best use of what I have?'. Constant switching is not the aim, because exploring has its own cost. And some commitments are worth keeping for reasons of loyalty or meaning; what matters is that those reasons are named.
A real-life example
An editor at a publishing house in Kadıköy, Istanbul, compares a quarterly magazine that breaks even and takes forty percent of her time with the audiobook line that time could build. The magazine comes last; it becomes a twice-yearly online issue, and she takes on the audiobook project.
How to use it
- 1When you review a commitment, write down the best alternative use of the same time and money, not just 'stop'.
- 2Set aside a small, fixed amount of time for exploring outside your main work, so that your alternatives stay real.
- 3If you keep something for loyalty or meaning, write that reason down.
