Context switching is killing your productivity (here's what to do about it)

It includes:

• Large chunks of focused “flow” time for more demanding projects.
• “Themed” days to reduce the need to recalibrate between different tasks.
• Advanced planning so you can prioritize meaningful work.
• Realistic time set aside for admin, communication, and meetings.
• Clear expectations for your teammates so they know when not to interrupt you.

You can’t expect to focus non-stop on a project for days on end. But at the same time, you won’t see any real progress if you mindlessly jump from one task to another.

You need a work schedule that pairs periods of sustained focus with rest in a way that’s purposeful and powerful.

... to reduce FOMO and productivity guilt. This will also help you to stay in the same mental space without worrying about what needs to be done:

• Go through your main tasks and divide them by either project, task, client, or topic. 
• Divide those tasks into two categories based on their connection, an A and a B schedule.

... and use office hours to keep your focus throughout the week. One example is the Free, Focus, Buffer system popularized by business coach Dan Sullivan:

• Free days are completely separated from business activities.
• Focus days are spent on your most important work.
• Buffer days are for planning, admin, and busywork.

Split your day between Maker and Manager time:

• Managers cut up their day into one-hour intervals (or less) and bounce between tasks.
• Makers need long stretches of uninterrupted time (usually at least half a day at a time).

To protect your focus, try to schedule at least a bit of Maker time into each day.

• Examine your current schedule (if you have one). Get real with where your time goes each day. 
• Communicate with everyone about how your schedule is going to change and why it’s important.
• Experiment to find what works for you. There’s no one perfect scheduling or time management strategy.
• Focus on your health.
