Use the Pomodoro Technique
Most people aren’t aware of this technique, but it is incredibly helpful. A technique developed by Francesco Cirillo in the late 1980’s can be helpful with everything from studying to regular daily work. You work in twenty-five minute increments, and after each take a five minute break. Stretch your legs, walk around the house a bit, do some sit-ups. Get your blood moving in some way, then go back to work.
