The Perfect Notebook is a modular, customizable notebook and task manager designed to help you achieve your goals and work-life balance, using a four-step system: PLAN, ACT, MONITOR, REFLECT. Packed with unique productivity tools, the notebook was created based on the guidelines developed by Dan Ariely, Professor of Psychology & Behavioral Economics at Duke University. What's unique about us? The Perfect Notebook never runs out as you can add, remove and rearrange pages any way you want using a modular disc binding system. Furthermore, it allows you to incorporate "BIG BLOCK" tasks everyday, prioritizing them with the color design, parallel to regular day-to-day tasks.
