 The pomodoro technique is a time and focus management method which improves
 productivity and quality of work. The name comes from a kitchen timer, which
 can be used to keep track of time. In short, you are supposed to focus on work
 for around 25 minutes and then have a well deserved break in which you should
 relax. Then when this cycle repeats for the fourth time you should take a
 longer break (have a walk or something).
