There is alternative to Pomodoro technique, but my question to you is have you implemented the technique properly to make it successful? Many people overlook the additional stages and simply focus on the main work blocks and breaks. Using the five stages of the Pomodoro Technique means that you are continually improving your performance and not just getting through the day’s work.
The Flowtime Technique is a good alternative.
