I am a high-energy person. But I haven’t always been that way. There have been times in my life when I was utterly exhausted. Times when getting through the day was a big chore. Times when I had nothing left to give by the end of the day. Times when I just wanted to collapse into bed and pull the covers over my head.

But in recent years, I am been very deliberate about managing my energy level. I did a lot of reading on this and took the time to educate myself. I experimented. I tried some new things. I broke some old habits. Now, my energy level remains pretty constant through the day.

Recently, I was preparing to deliver a speech and found myself in a funk. I was experiencing an unusual amount of distraction and self-doubt. Fortunately, I had about four hours before I was to go on stage. So, I decided to call my wife, Gail.

She instantly knew I wasn’t in a good place. (This is one of the many benefits of long-term marriage. My wife can read me like a book.) After listening to me whine for a few minutes she said, “Okay, I want you to hang up and go for a run. Call me when you are done.”

We all know the physical benefits to running. I won’t waste your time by repeating them here. However, people who don’t run, often miss the non-physical benefits. To me, these are even more valuable than the physical ones.

This week, I have been running outdoors. I have chosen to run in the heat of the day—usually when the temperatures are 90° or more. I know, I’m crazy. But I am loving it.

Sometimes, you get stuck in a funk and can’t figure out why. Maybe it is something tangible and specific. Maybe it is nothing in particular.

For example, a month ago, we had two gorgeous weeks of spring. The temperatures were in the 70s, the birds were singing, the daffodils began to bloom. I caught myself whistling as I was leaving for work.

Too often, we seem to accept the fact that our energy level is what it is. It’s beyond our control. Not true. Like most things in life, we have more control than we think.

Recently, just for the fun of it, I started making a list of all the things that energize me. I started out with a list of 10. Then it grew to 20, 30, then 40, and now, 44. But I am certain I have only just begun.

Several months ago, Gail and I were sitting in the den after a quiet dinner. I had been traveling extensively, and this was the first evening I had been home in days. I said to her, “I don’t know what it is, but I feel really discouraged.”

On a recent Catalyst Podcast, Andy Stanley said, “The best thing a leader can bring to his team is his energy” (quoting Bill Hybels). I agree. This has certainly been my experience.
