Just read an interesting article/report from the Harvard Business Review on Manage your Energy, Not Your Time.
The premise is that time is finite, energy is not. You can get more done in the same amount of time if you have the energy to do it. The article comes at it from a management/organizational approach, but there are tips and ideas here to help not only within your organization but also your personal life.
Now who couldn’t do with more energy these days? I know I can!
