You don’t currently have a mobile device, so you’ll use paper printouts to stay focused away from the office. Print your tasks each day (Do Today list if available), take the list with you, and mark it up. Drop it in the Inbox for later processing when you return.
Consider getting a smartphone to make your life even easier. A good smartphone lets you see and manage your tasks all the time, anywhere, and there is nothing to process or update at the end of the day.
