Set time aside during your mornings for tasks that require thinking, planning, or creativity. Early in the day, when your attention is at its best, it is easier to make meaningful progress on work before distractions arise.
During this period, do your best to avoid email, chat, and notifications. If you use a shared calendar with colleagues, block this time out so they can see that you’re unavailable and, hopefully, less likely to interrupt you.
After your focused work period, the rest of the day often becomes more externally driven. As hours pass, decision-making, interruptions, and constant task switching gradually drain attention. By handling your most demanding work early, you avoid competing with that mental fatigue later on.
