The specific milestones here are certainly up for debate, but the general approach to thinking this way is a good one in my opinion. I read Quit: The Power of Knowing When to Walk Away by Annie Duke last year and found it quite illuminating, both in introducing this concept of having “kill criteria” like this to help clarify why we are doing things and when it’s “okay” to quit, and also in exploring the scope of social/cultural bias we have towards sticking with losing propositions at the expense of trying new things. Social pressure to not be viewed as a “quitter” is quite a powerful force, and it distorts our thinking about what we really want to achieve.
