When we say 'organize' your schedule we mean to organize it so that no time is wasted. Try grouping similar tasks together so that you don't have to change gears as often. If you are scheduling appointments that you have to drive to; make sure that you block times for the area that you will be in, so you are not driving all over town.
Prioritize your schedule. What are the most important things for you to accomplish that day? Make these your top six tasks. If something lands on your schedule that is not important or urgent then eliminate it (refine).
