Risk & uncertainty · Lesson 6 of 6

Knowing when to quit

Deciding in advance what would make you stop protects you from both giving up too early and holding on too long.

Free — no account needed to read

Persistence is admired, and rightly: many good things take longer than expected. But there is a quieter skill that matters as much, which is recognising when something is not going to work and letting it go before it costs more than it can ever return.

The trap is that the longer you invest in something, the harder it becomes to stop, because stopping feels like wasting everything already spent. That earlier effort is gone whatever you choose now. The only real question is whether the next month of effort is worth it.

The simplest protection is to set your quitting conditions at the start, while you can still think clearly: if by this date I have not seen this sign, I will stop or change course. Writing it down makes it much easier to honour later, when emotion runs high.

See it happen

Sanjay has spent eighteen months building an app in his evenings. Very few people use it, and he is exhausted, but he tells himself he cannot stop after so much work.

The first reaction

Giving up now would mean the last eighteen months were wasted, so he feels he owes it to himself to keep pushing.

With the idea

He asks a different question: knowing what I know now, would I start this project today? The honest answer is no. He writes down what he learned, releases the code, and puts his evenings into something with more promise.

What changed

He judged the next month on its own merits instead of on the months already spent.

Easy to take the wrong way

This is not a case for quitting whenever it gets hard. Difficulty is normal. The signal to stop is evidence that it will not work, not the feeling that it is uncomfortable.
