The Pomodoro Technique
The Pomodoro – Italian for tomato, or a kitchen timer in the shape of a tomato. In eXtreme Programming (XP) teams, a pair would set the timer to 25 mins for a focused pair programming session, and then the pair takes a mandatory 5-10 m break before setting the timer for another pairing session.
Working in a focused manner has been very helpful in clearing my cluttered mind, and I get to work through a chore or kick back on my chair and tinker through a problem. Because I know I can get up when the Pomodoro is over, I feel relieved that I have only one thing to do right now.
