Are distractions and multi-tasking undermining your productivity work? Do you have a task that you hate to do, but must work through it? The Pomodoro Technique may work for you. Wikipedia provides some background information: "The Pomodoro [T]echnique is a time management method developed by Francesco Cirillo in the late 1980s. The technique uses a timer to break down periods of work into 25-minute intervals called 'Pomodoros' (from the Italian word for 'tomato') separated by breaks. Closely related to concepts such as timeboxing and iterative and incremental development used in software design, the method has been adopted in pair programming contexts. The method is based on the idea that frequent breaks can improve mental agility."
The Pomodoro Technique has an official website. I use this method to organize my own work. It's particularly useful for creative professionals and students. If you've got a short attention span or you want to cut down on your procrastination tendencies, then this method may work for you. Through concentrated focus, it helps you to stay focused on the single task at hand.
Here are some free resources to get you started. You can also find plenty of free Pomodoro Technique web and smartphone apps on the web. This is the free web-based one that I use.
