The 2-Minute Rule: How to Clear Mental RAM

You have an email you need to reply to. It will take 45 seconds. You flag it. You think about it. You worry about it. You archive it. You search for it later.

You just spent 10 minutes managing a 45-second task.

The Rule (David Allen)

From "Getting Things Done" (GTD), the rule is absolute:

"If an action will take less than two minutes, it should be done at the moment it is defined."

Why It Works: The Zeigarnik Effect

Psychologist Bluma Zeigarnik proved that our brains remember incomplete tasks better than completed ones. This creates "Open Loops".

Every email you "save for later" is a tab open in your brain's browser. Eventually, your browser crashes (Burnout).

Closing the loop instantly frees up RAM.

The Advanced Variant: The "Start" Rule

For big tasks (like "Write Thesis"), the 2-Minute Rule fails. You can't write a thesis in 2 minutes.

The Hack: Scale it down. "Open the document and write one sentence." That takes 2 minutes. Once you start, physics takes over (Newton's First Law). Objects in motion tend to stay in motion.
