List Impossible is a to-do list

Create a list and an expiration timer

The list self-destructs when the timer reaches zero

Keep track of your performance

You can only create 1 to-do list at a time so it forces you to focus on the task at hand. The list self-destructs after your timer expires giving you a sense of urgency to complete your tasks.
