To-do lists improve productivity, but they can add stress if they multiply on Post-It notes, 3x5 cards, and paper scraps. Avoid flipping through this stuff. Instead, keep one master list. Update it, and transfer undone items to a clean sheet as needed. Supercharge a to-do list with five sections: job, family, friends, leisure, and personal/health. Fit everything into one of these categories. Prioritization will be easier, and you'll reduce time spent on trivial tasks. Anxiety will lessen as you get more done!
