Especially for my writer friends (but nonwriters can steal these tips), before you leave your desk for the day or night:
BACKUP YOUR WORK: In two places is best. I use OneDrive and a thumb drive, then once a month I back up to an external drive I keep in a water and fireproof small safe.
CLEAR OFF YOUR DESK: Put everything away and file anything that needs filing.
CALENDAR: Make sure everything is written on your calendar and check to see if you have any early-morning appointments.
TO-DO LIST: Be very systematic with your to-do list. Quickly write down everything you hope to accomplish the next day, but then put everything in order of priority.
DO ONE EXTRA THING: If needed, for example, write one email you owe. Deal with one piece of paper you’ve been hanging onto. Make a quick phone call you’ve been putting off.
Did I leave out anything anyone thinks is also important? Let me know in the comments!
