A schedule can help make sure you are varying your job search methods and sources as well as following up and networking. It doesn't have to be anything fancy - it can be as simple as making a list of things you need to do and sources of jobs and divvying them out over the course of the week.
Having a schedule also ensures that each day will be different and give you some relief from the non-responsiveness of your computer! It is important to write your schedule out and to refer to it the evening before and the morning you start your job search. Have it available throughout the day to help you stay focused.
