The Pomodoro Technique™:
"The basic unit of work in the Pomodoro Technique™ can be split in five simple steps:
1. Choose a task to be accomplished
2. Set the Pomodoro to 25 minutes (the Pomodoro is the timer)
3. Work on the task until the Pomodoro rings, then put a check on your sheet of paper
4. Take a short break (5 minutes is OK)
5. Every 4 Pomodoros take a longer break"
