Taking advantage of your "good hours", when you have the most energy, to focus on what you need to get done is great for your productivity. Expand this idea to your whole work week by figuring out which days work best for the tasks on your plate. For example, you might schedule important meetings or brainstorm sessions for the middle of the week when energy is generally high, and low key tasks for Friday. Jeremiah Dillon, head of product marketing for Google Apps for Work, explains how he applies this to his week:
Monday: Energy ramps out of the weekend -- schedule low-demand tasks like setting goals, organising, and planning.
Tuesday, Wednesday: Peak of energy -- tackle the most difficult problems, write, brainstorm, schedule your Make Time.
Thursday: Energy begins to ebb -- schedule meetings, especially when consensus is needed.
Friday: Lowest energy level -- do open-ended work, long-term planning, and relationship building.
Adjust this plan based on your own energy levels. Just because Tuesdays are peak energy for many people doesn't mean you should force yourself to tackle tough tasks then. However, keep in mind what days may be generally best for everyone if you're planning meetings or tasks that involve others.
