1. No reward if you get distracted. It is important to focus for the entire interval. Therefore, a box will not pack automatically when timer finishes. You have to do it manually. Otherwise, it will overflow and break apart. Such broken (distracted) box will remind you of the time when you “almost” made it. 2. Reminders of a time flying by. Distractions are inevitable, our goal is to get back to focus sooner rather than later. Once you get distracted, time starts flying into the trash can. The longer you get distracted, the more trash cans you collect. Take them easy, those trash cans aren’t supposed to make you feel bad. Their goal is to motivate you to get together and get back to work sooner.
