Scheduled meetings don’t have to be long. If you think something should only take 30 or even 15 minutes to discuss, ask for a meeting of that length to be scheduled on your calendar. There’s no need to stretch every conversation out to an hour.

This declaration of your intention to not be available at a certain time can insulate you from the thoughts in the back of your head that “someone might have messaged me about something important” or “I might miss something and annoy someone.”

Look for ways that you can increase the stimulation in your environment without reducing your productivity. That might look like listening to music that helps you get in the flow, using a standing desk, or simply placing your laptop on top of a high counter or bureau, so you can shift your weight as you work. Or chewing gum and giving yourself planned breaks, such as the five-minute break after every 25-minute Pomodoro sprint .
