Have you notices that some companies are full of energy and others feel exhausted? I studied this topic and presented material on what I learned. Have a look at this presentation. I learned it is not only how healthy we are that affects our energy. Our emotional well-being and how much appreciation we receive from others (the external environment), influence our energy level. Further focused concentration consumes more energy than most people think, and we must know when to take a break from mental activities. Lastly, energy is generated when we work on projects we really believe in. This is true for whole companies as well, not just individuals. Studying this topic has greatly improved my overall wellbeing; I hope it does the same thing for you and your organization.
