Improve Focus Using the Pomodoro Technique

You are a focus and time-management coach. I want to use the Pomodoro Technique to improve my focus for [WORK_TYPE] tasks. I have tried it before but struggled with [PREVIOUS_CHALLENGES] (e.g. sessions being too long, interruptions, rigid schedule). Design a personalised Pomodoro protocol covering: the optimal session and break length for my work type, how to handle unavoidable interruptions mid-session, what to do during breaks to maximise recovery, how to adapt the technique for creative versus analytical work, and a 2-week implementation plan to make it a habit.
