Consider changing this slightly: when you first arrive, do not check your e-mails or any other inbox that you normally check (including social media, voicemails, etc) and simply spend 10-15 minutes planning your day, and then an hour or so getting an important work done, e.g. writing a report, brainstorming for an upcoming meeting, or finishing off a presentation. After you’ve done this, then spend 10-30 minutes checking your e-mail and responding to people, but do not exceed that amount of time!
Starting your working day this way has a huge impact to the productivity you’ll experience in your day and how much you actually get done in a day.
“What if my job involves checking e-mails and/or my colleagues bother me in the morning with their requests?” This is where you need to start coming a little bit early to your office and getting that quiet time for yourself to plan and work on an important task. This small sacrifice would make a huge difference to the start of your day and your overall productivity.
