The work I do causes me to think a lot about how and why culture changes, how businesses change to respond to cultural change and how we, as individuals, adjust engagement and consumption behavior in reaction to an external disruption–that change in our normal state–when it is forced upon us. Throughout my career, I have helped many companies facilitate change, and the most important thing I’ve learned from it all is most of us hate change because it is usually something we are forced to react to, rather than participate in. This is especially true in our workplaces, with the businesses we deal with, and even with our favorite products. If you need an example, consider “New Coke,” or the attempt by GAP to change its logo.

I think everyone realizes change is constant and there is no rational choice but to embrace it, evolve with it, or at least find a way to adapt to the impact it has on our work. Embracing, evolving, or adapting is how most of us manage change in our personal lives, too. Although, we probably manage change in our business and professional lives much easier than we do in our personal lives.

My friend, Wendy Lou, believes most of us just want someone to change with us. I believe this, too, and I think this is why a change in business and professional environments, as painful as it is, can feel much easier for us than personal change. While each of us may approach change differently based on our background and life experiences, we typically experience workplace change with colleagues who are all moving, together, in the same direction. Change is much easier to navigate and appreciate if others are with us on the journey.

In our personal lives, we typically tackle change, at least self-change, alone and this is precisely why such change can be difficult. When we need, or desire, change of our own it’s often self-driven or created by an internal disruption and not directly caused by external forces. When we have people in our lives who are capable of and willing to change with us, we can grow together. If not, then, unfortunately, we will grow apart.

Facilitating life change is intensely personal. After all, not everyone experiences change the same way, or at the same rate. Unlike in the work or business world, we are not all moving in the same direction or toward the same goal, at least not at the same time, in our personal lives. While others might empathize and support us on our journey, no one will truly understand our new path because they will navigate the unique twists and turns of their own path at a different pace.

Change is inevitable. Accepting our own need to change and evolve is an especially difficult, but necessary part of what it means to be human. Acknowledging that we may need to experience personal change alone surfaces the undeniable, and sometimes painful, recognition that we are solely responsible for who we are, who we will become, and the happiness we choose to uncover in the process of living our own lives.

Yesterday I was reminded my body has an expiration date. I know I will die someday, but the dreamer who drives my soul doesn’t like to think of such things. The statistician in charge of my brain, on the other hand, does expiration mitigation calculations thousands of times per day. I just don’t like the reminders from the outside world.

While I remain hopeful for at least fifty-one more years of life, I recognize living to be 100 with a sound mind and body is an unlikely possibility, especially since both are already questionable. Despite the fact I aggressively manage my health, there are hundreds of non-health related reasons that could end my life well before my planned expiration date. This is troubling to me because I still have things to do, people to see, places to go, and trouble to cause. I don’t want to run out of time before I’ve accomplished it all.

My arrival at middle age a few years ago came with a piece of baggage labeled, “oppressive sense of mortality.” The luggage is scuffed, tattered, and covered with stickers from travels around the world. Its hinges are worn from the constant opening and closing. Bungee cords hook together over latches that no longer have the strength to hold the baggage closed. It’s ugly, this baggage, and still I’m compelled to look inside for whatever answers it might hold.

I’ve learned from my far too frequent peeks inside that my first twenty-four years of life were for learning the basics for living, and my last twenty-five years were for creating a life. The baggage shows my future, too, swirling amongst all of my hopes, dreams, and plans—those I’ve accomplished and those I now wonder if I ever will accomplish— without a clear direction or any certainty of duration.

Perhaps the most important thing the baggage has shown me is while the past is clear, the future is always uncertain. I’m reminded that although I am not now, who I will become, I am also no longer who I once was—the big dreamer with a lifetime of opportunities. The luxury of time is no longer on my side.

I still dream the big dreams and I still have things to do, people to see, places to go, and of course, trouble to cause. I’ve just realized the dreams I had then—the dreams of a young man—are no longer the dreams I need, or frankly want. The seconds of life are far more precious now and I don’t want to waste them on aspirations I know are completely unrealistic or unattainable.

I have many unfinished castles in the sky today. The construction stopped some time ago and the workers have gone home for good. What remains of those castles was mortgaged to pay for the daily happiness I get from living more of my life in the moment and much less of it with my head in the clouds.
