One of the most productive steps for the day ahead is starting the night before. Your mind is already buzzing with everything you need to do tomorrow anyway so just write it down. Need more incentive? Writing a to-do list can actually be a stress reliever by visualizing all that needs to be done the following day. It works. It's science. Just ask Mo Seetubtim, founder of the sought-after Happiness Planner.
