Write down a list of things you can conceivably accomplish in a day. Once you have a concrete list in front of you, it's a lot easier to get started and stick to a plan. This also helps you easily transition between tasks since you won't have to ponder what's next.
Keep your list and schedule in a spiral notebook. Check off or put a line through each job as you complete it. When you look back at all you've accomplished, you’ll feel great!
