The best tool for time management is probably one of the simplest tools, and that’s having a schedule. You can do that on paper or with a phone or Outlook — whatever electronic versions work best. Taking the time to actually schedule is really the key. Scheduling time to actually go through your calendar and fill it up. I find when my calendar is empty, I often will wander off to different tasks or get distracted with email or maybe just think about all the things there are to do instead of actually getting them done. Having time set aside to schedule and plan is a pretty critical part of scheduling.
The more you can schedule blocks of time in a repetitive sort of manner so that you can get into a routine, then you can really find that the schedule works well for you and becomes a natural process. One of the best ways that I find to actually get things accomplished would be if you schedule time out of the office, maybe at a coffee shop or take yourself to lunch, and that can be a great time to use for actually planning your schedule and planning time ahead.
