review it each week or each month, which is more practical than tracking it every day. Second, manual tracking should be limited to your most important habits. It is better to consistently track one habit than to sporadically track ten. Finally, record each measurement immediately after the habit occurs. The completion of the behavior is the cue to write it down. This approach allows you to combine the habit-stacking method mentioned in Chapter 5 with habit tracking. The habit stacking + habit tracking formula is: After I [CURRENT HABIT], I will [TRACK MY HABIT].
