Parkinson’s Law states that work expands to fill the time available, and it’s so true! How much work do you get done right at the end of the day, or the days leading up to a holiday? SO MUCH MORE! Because you’re focused and you are restricted in what needs to be achieved.
I love the Pomodoro Timer, which is a super-simple technique of setting a timer for 25 minutes, working uninterrupted for that period, taking a 5-minute break, and repeating for 3 / 4 times before a longer break.
