Even if you can't make a decision on the issue, make a decision about the memo, and move it off your desk. Rather than keeping material on your desk, Toss any valueless material immediately. Junk mail might fall into this category, but so might many For Your Information memos, and other reports that are sent to you on a regular basis but require no action on your part. There is no need for you to act on each piece of paper that crosses your desk. Whenever possible Refer to someone else for action, making sure you provide sufficient information so the person handling the action knows what you expect.
Some material requires immediate action.
When you sift through your paperwork, identify items that you can take action on immediately, where action will NOT require large investments of time. It is often useful to schedule the time needed to complete the required task. Material that requires no action but needs to be retained can be placed in the to file folder. Short items can be read immediately. Anything not falling into one category or the other should be tossed.
