The human brain can't work without breaks and if you plan a precise objective with a specific amount of time dedicated to this objective you'll be more productive.

Therefore work for 60 to 90 mins on a task and then take a 5 to 10 min break to do something else.

You can also use the POMODORO method.

It's very simple:

- choose a task to accomplish
- Set the Pomodoro timer (25min):
- Work on the task for 25 min
- Take a 5min break
- Every 4 Pomodoros take a longer break
