Clear off desk. Similar to the filing tip above, but this applies to whatever junk you’ve got cluttering up your desk. Or on the floor around your desk. Trash stuff, file stuff, put it in its place. A clear desk makes for a more productive you. And it’s oddly satisfying.
Outline. Similar to brainstorming, but more formal. I like to do an outline of a complicated article, report or project, and it helps speed things along when I get to the actual writing. And it only takes a few minutes.
Get prepped. Outlining is one way to prep for longer work, but there’s a lot of other ways you can prep for the next task on your list. You may not have time to actually start on the task right now, but when you come back from your meeting or lunch, you’ll be all prepped and ready to go.
