Margin: if your plan only works when everything goes right, it's not a plan

Margin is DAMM's third pillar and answers a simple but often ignored question: if something changes, do you still have room to maneuver?

Margin as the capacity to stay in the game

DAMM treats margin not as comfort, but as the capacity to stay in the game. A choice that only works if everything goes right isn't a solid choice: it's a pact with luck.

Margin is measured in resources: time, money, energy, relationships, open options. When a decision consumes all these resources, you're not deciding — you're gambling.

Three types of margin

1. **Financial margin**: do you have enough reserves to withstand a negative outcome without entering crisis?
2. **Time margin**: do you have time to correct course if something doesn't work as expected?
3. **Emotional margin**: do you have the psychological energy to manage consequences if things go differently?

Margin that erodes without you noticing

Slow damage is essentially margin erosion. Every small concession, every accepted compromise, every "it's fine for now" reduces available space. When margin reaches zero, any unexpected event becomes a crisis.

Rebuilding margin

Rebuilding margin doesn't necessarily mean making big changes. Often it means stopping small things that consume it. The Minimum Move — DAMM's fourth pillar — is the tool for rebuilding margin without exposing the entire system.
