One of the most important principles about using time well is to focus on one thing at a time. It’s hard to focus, though, when you have dozens of thoughts running through your mind at any given moment.
For example: Contemplating the ingredients you need to pick up at the grocery store later today, thinking about an edit to an article you need to make, and considering which summer program to send your kids to – all keep you from concentrating on the report you’re trying to finish right now.
If you don’t pay appropriate attention to what has your attention, it will take more of your attention than it deserves. – David Allen
I’m not suggesting that you stop your work and finish each of the tasks that are nagging at you; instead, get them out of your mind and into someplace where you can take action on them later. For me, that means putting them in my electronic calendar as an appointment. For you, it might be a list in your phone.
Whatever method you use to get things off your mind, make sure you turn them into actionable items. It beats jotting ideas on a sticky note that you end up losing under a pile of paper.
