Design Your Kill Criteria

Set your stop conditions before you start. The pre-mortem — imagining failure before it happens — is the most powerful bias-breaker in your toolkit. Write it before you need it.

Part 1: Design Your Kill Criteria

+5 XP on completion

Scene 1

Before starting any project, write the criteria that will end it. Most people never do this — and pay for it.

Scene 2

Kill criteria are the conditions under which you stop — no exceptions, no extensions, no emotional override.

Scene 3

Why set kill criteria? Because sunk cost traps are emotional, not logical. Logic written in advance beats emotion in the moment.

Scene 4

The Pre-Mortem: imagine it's 6 months from now and the project failed. What happened? Write it down now, before you start.

Scene 5

Pitfall: writing kill criteria you'll secretly ignore. Share them with someone who will hold you accountable.

Scene 6

Kill criteria prevent the sunk cost trap. They are acts of future-self wisdom written by your present-self clarity.

Part 2: Write Your Pre-Mortem

+10 XP on completion

Scene 1

Kill criteria protect you from your own future emotions. Today you write yours for a real project.

Scene 2

Today's practice: take one active project. Write three things — success criteria, timeline, and kill criteria.

Scene 3

Section 1: what does winning look like? Be specific — a number, a milestone, a clear outcome.

Scene 4

Section 2: by when? Section 3: if [X] happens, I will stop. Fill both in before you close this page.

Scene 5

Commit: share these criteria with one person who will hold you accountable. Accountability makes criteria real.

Scene 6

Your compass sees most clearly when you look through the lens of honest criteria. Clarity is the final refinement.
