The 5-minute rule: start embarrassingly small
The most common mistake in habit-building is starting too large. You decide to meditate for 30 minutes, read for an hour, or go running every morning. These are admirable goals — but they require a high-energy version of yourself that may not show up every day.
The 5-minute rule solves this. Your only commitment is to do the habit for five minutes. Five minutes of journaling. Five minutes of movement. Five minutes of focused work on your side project. The goal is not to do five minutes of work — the goal is to show up. Once you are already started, the friction of continuing is near zero.
James Clear calls this "the two-minute rule" in Atomic Habits. BJ Fogg, author of Tiny Habits, calls it "anchoring" to a tiny action. The science behind it is the same: lowering the activation energy for a habit makes it easier to initiate, and initiation is the hardest part. You can always do more once you have started. You cannot do more if you never start.
