Personally, I am most wide awake, energetic, and focused early in the morning. Except my morning hours are usually sucked away by reading email, putting out fires, and being in meetings. Once I realized I was wasting these beautifully productive hours in things that did not require my absolute full attention, I started blocking off my precious morning hours for doing my most important things first, and moving the less important stuff later.
How about you? Have you taken notice of when you are most productive and worked to block off this time for yourself?
