The protocol

Pick one habit

Build or break. One thing. No portfolio of half-attempts.

Check in daily

Every day you survive, you stamp the grid. Streak grows. Survival Meter holds.

Don't fold

Hit the panic button when you're about to break. Survive the urge. Repeat 66 times.

[ WHY 66 ]

Not 21. Not 30. Sixty-six. We didn't make that up — researchers did. We just made it impossible to ignore.

One habit. 66 days. No refunds.
