Start the morning by setting a timer on your phone for 10 minutes. Flip through your inbox and mark the most important emails that need to be addressed right away. Deal with them. Then, shut off your email and get to work on something that requires your undivided attention. You can return to your email afterward.
If you’re going to start your day by engaging with some important task, end your workday by preparing for that work. Take out any folders, papers, or other physical objects related to the task and leave them by your work computer. Have a list of the computer files you’ll need.
