Of all the sources of fire, I’ve concluded that perhaps the biggest is sheer unadulterated love of the doing. It’s like a personal flywheel within: If you discover something you’re encoded for and you love doing it, then you can't help but want to do more of it, which means you can't help but get better at it, which means you can't help but move toward the intrinsic satisfaction of excellence in what you do, which further reinforces doing what you are encoded for and love to do.

But as I got deeper into this research, observing the vast differences across the people in this study and how they flourished at their best when life lined up with their encodings and what fed their inner fire, I gradually began to change. Subtly at first, I began to shift away from trying to change people into what I wanted them to be. Simultaneously, I shifted toward finding or creating the best possible match between their encodings and their responsibilities. It didn’t happen overnight, it was more of a managerial form of simplex stepping. I’d sense something about a person’s encodings, and then I’d make a shift in their responsibilities to fir those encodings. Then I might observe something else about their encodings, discovering something wonderful about them when they thrived in a task, and I’d make another shift in responsibilities. Together, we essentially simplex stepped toward them coming into frame in a seat on the bus.

Extending out feeds the inner fire by animating the human yearning for growth, learning, discovery, and challenge; it activates the joy of self-development, capturing the youthful energy that comes from starting anew. Extending out can reveal previously hidden encodings; a continuous process of discovery that feeds the inner fire. (Wow, that’s exciting— I never knew I had that inside me!) Circle back also acts as a source of reinvigoration, but in a different way. Circling back reframes big bright encodings discovered long ago, which also feeds the inner fire. To circle back by tapping encodings discovered earlier in life is like refueling for the next phase if extending out.

I seem to have at least as much energy at 67 as I had at 37, perhaps even more. I need less sleep. I feel on the balls of my feet, tilted forward. I can't wait to get up before 5 a.m. and throw myself into each day. The inner fire burns brighter than ever. There are multiple elements that feed into this, including the sheer good luck of health to this point in my life. But now I see that one huge element has to do with this very project being an invigorating fusion of Extend Out/Circle Back. By taking on an entirely new subject at this stage of life, shifting from studying what makes great companies tick to studying people and what makes their lives tick, I’m clearly extending out. At the same time, I’m also circling back, returning to encoded operating modes I discovered years ago, particularly my penchant for doing big research projects, going from chaos to concept, and then writing and teaching what I learn. I’m incredibly energized by discovering entirely new elements of myself in doing this project and by how the study itself has changed me in such profound ways. I’m equally energized by circling back to activate and reactivate interests and encodings I’d discovered long ago.

I don’t think of the people in this study as inspirational; I think of them as inspired. I don’t aim to inspire you to be exactly like any of the specific people in this study. I hope, rather, that you’re able to find yourself clicked into frame, inspired by what fits your encodings and ignites your inner fire, and that you commit to pursue it with excellence.
