The biggest benefit to setting up the night before, is that you get to spend the first 2-3 hours of the morning being present. You will not be scanning your brain for what to do next, torturing yourself with deadlines and situations that are out of your control. Instead, the longer you can keep your mind on the present, the more focused your work will be and less stress you will feel, and you will actually get more done. As an added perk, you will be happier.
