At Your Best, by Carey Nieuwhof

Find your zones! Where are you most productive? 

If you're a leader, you are responsible for knowing your most productive times but also the most productive times of those on your team.

Like anything with personal development, this should not be used as a crutch. We don't say "well, I'm not productive at this time so I'm never going to do anything in this space." We can have high, average, and low levels of production times throughout our day, but these will flex and change with the seasons we are in.
