 Played piano after midnight, and then worked until 3. Watched a football game and then did a cycling exercise around 5. Watched a course video after breakfast, then went to sleep. Got up at 11:30 to have lunch, but couldn't fall asleep later, so worked for some time instead. Slept from 3 to 5:30. Worked after dinner. Slept around 6 (3.5 + 2.5) hours and completed 18 pomodoroes today - three for exercise, five for learning, and ten for work.
