Years ago I read the book The Power of Full Engagement. Managing Energy Not Time is the key to high performance. It made total sense to me that your output is reduced the more time and energy you expend without renewal.
The last two days have not been my best. In fact they've seen me revert to my old ways of focusing on my things and my things only. As I sent the last email last night at 9:30pm after sending the first email at 4:30am I was waisted. In between I'm not sure what totally happened but I can assure you that the quality of my output was not great. I know that for sure with everyone I touched yesterday.
I'm sure glad I can catch myself now and come back to what I know.
It's a good life....
