I’ve spoken in the past in different places about time management and energy management, which is something I borrowed from the book “The Powerful Engagement” where it says the purpose of time management is indeed energy management. As you get older, you understand more and more that if you’re not careful, you can find yourself with more time than you have energy, which is a weird feeling. From time to time, I’ve actually had that happen to me.
What I’ve discovered lately is different categories of energy in your life. You can still have great physical energy and be able to go out and work hard or go do some exercise, but there just doesn’t seem to be a lot of juice upstairs mentally.
