Start your day doing the Most Important Task (MIT) first.

Write your goal down.
Be specific.

Identify all the tasks/activities that are necessary to achieve your goal.
Write it down.

Circle the task that will have the biggest impact on your goal (MIT)
For example, although writing a book involves many activities like research and planning,  the biggest-impact task is the actual act of writing.

Schedule your MIT for the first two hours after you are fully awake
Most people are most productive and have the highest cognitive functioning within the first two hours after they are fully awake. By working on your MIT first thing, you do what matters most as your priority, setting yourself up for a successful day.
