To stay focused on your work you need to know the next action you will need to take. You should avoid putting down generalized goals/tasks such as eating healthy, instead break it down and put ‘I will eat a morning bowl of fruits three times a week. When you don’t have this direction, the likely chance you will procrastinate and not achieve your goal/task. When you are working on your task remember to take small breaks in order to prevent you from losing focus. Setting a timer for 25 minutes is also helpful so you can avoid any resistance to start working and convince your brain to stay committed on a task.
