Once you know what you’ll focus on, you’ll need a daily structure for staying focused on it. You may not be able to eliminate context switching from your day entirely, but these strategies will help you cut down on the number of times you have to shift your attention:

• Task batching : Grouping and performing similar tasks together. For example, answering all of your emails at the same time so you’re not bouncing back and forth between your work and your inbox all day.
• Time blocking : Dividing your day into blocks, such as “meetings,” “email,” and “deep work”. This method goes a step further than task batching and requires you to physically block off time on your calendar for a designated task or group of tasks and only those tasks.
• Theme days : Designating different days of the week for different types of tasks. This is a more extreme version of task batching and time blocking that allows you to focus on certain types of work on certain days and postpone other types of work that don’t fit with the day’s theme.
• Time boxing : Setting a limit on how much time you spend on a task. Similar to time blocking, time boxing requires you to designate boxes of time for specific tasks. The twist is that you must finish the designated task within the time box. The time constraint creates a sense of urgency that sharpens your focus.
• Pomodoro method : Setting a timer while working on one task and taking regular breaks. This is a variation on time boxing that calls for 25-minutes of focused work on a single, clearly defined task followed by a 5-minute break with a longer 30-minute break after every four focused sessions.
