Be flexible, because priorities often alter throughout the day, but make sure staff know if you change your mind. Revise timetables weekly and amend goals monthly. Make daily lists. Make a list of things to be done and cross off the tasks as you complete them. This will give you a psychological lift and help reduce the stress of trying not to forget everything you have to do - and the panic of remembering something missed.
Some people find list making useful even if they mislay the lists later in the day.
The simple act of having to plan the day ahead is enough. Use diaries or a spiral notepad so that tasks can be carried forward or reassigned to future days. Avoid losing valuable time taking things out and putting them away again. Rearrange your filing system and workspace so the most frequently used items are most within reach. If your work involves constantly moving around your office, install an extra-long telephone cord on your handset or buy a cordless phone.
