The 2-minute rule has two halves: if a task takes under two minutes, do it now; and to build a big habit, start with a version that takes just two minutes.
Why it works
Starting is the hardest part. A two-minute version removes the friction, and momentum does the rest.
Apply it
“Write a report” becomes “open the doc.” “Exercise” becomes “put on my shoes.”
Build the system
Pair it with a planning system that sticks.
