Monkeys and pedestals is a mental model that helps you quit sooner. Pedestals are the part of the problem you know you can already solve, like designing the perfect business card or logo. The hardest thing is training the monkey. When faced with a complex, ambitious goal, (a) identify the hard thing first; (b) try to solve for that as quickly as possible; and (c) beware of false progress. Building pedestals creates the illusion that you are making progress toward your goal, but doing the easy stuff is a waste of time if the hard stuff is actually impossible. Tackling the monkey first gets you to no faster, limiting the time, effort, and money you sink into a project, making it easier to walk away. When we butt up against a hard problem we can't solve, we have a tendency to turn to pedestal-building rather than choosing to quit. Advance planning and precommitment contracts increase the chances you will quit sooner. When you enter into a course of action, create a set of kill criteria. This is a list of signals you might see in the future that would tell you it's time to quit. Kill criteria will help inoculate you against bad decision-making when you're "in it" by limiting the number of decisions you'll have to make once you're already in the gains or in the losses. In organizations, kill criteria allow people a different way to get rewarded beyond dogged and blind pursuit of a project until the bitter end.

What makes a decision great is not that it has a great outcome. A great decision is the result of a good process, and that process must include an attempt to accurately represent our own state of knowledge. That state of knowledge, in turn, is some variation of "I'm not sure."

Essentially, regardless of the history they have with the decision, they ask themselves, "If I were approaching this decision fresh, would I want to enter into this course of action?"
