What do you know about your Energy Levels?

Had an interesting conversation with a former client yesterday – we got to talking about energy levels vis-à-vis time-o-day.

“I’m a morning guy," he said, "so I like to work out in the evening.”

Counter-intuitive thinking like that fascinates me. Turns out that although he likes to "hit it hard" at the gym, working out is relaxing for him - something he'll do anyway. So, he prefers to focus his high energy periods on work, rather than working out.

Now I consider myself pretty self-aware on a lot of levels, but I have to admit that I have only a very basic sense of how my energy level relates to time-o-day. For me, it seems to be more a function of what I’m doing, or planning to do, rather than when I'm doing it: If it’s "important" work, or fun, my energy tends to run high; if there’s not much on my plate, not much energy.

How about you? What do you know about how your energy operates?
