The Seven Year Itch, a 1955 Billy Wilder film with Marilyn Monroe and Tom Ewell, surfaced an idea that had burbled along for some time in pop culture. To wit: married couples experience a decline in satisfaction over the first four or five years and, by year seven, tensions have risen to the point that they either divorce or adapt to each other in new ways. Some social scientists pooh-pooh the notion, but others have documented the phenomenon.
I’ve been in the people business a long time and I think they’re on to something that affects not just our marriages, but every aspect of life. Calling it the seven year enthusiasm curve or passion cycle may be more accurate. But knowing what it is and how to deal with it can definitely increase your quality of life, may help you make better job choices, and might even save your marriage.
The burnout cycle in a nutshell: First, initial enthusiasm about a new idea, person, job, or ministry. We find something or someone new and fall in love. Second, energetic commitment to it, we go all in. Third, sustained effort for two or three years, we work hard at the new thing or new love and enjoy it. Fourth, inevitable problems emerge and the new thing starts to feel old, the gears grind, effort required increases as enjoyment declines. We hang on a couple more years, wondering where the love went. Fifth–and this can happen anywhere between years five and seven–the thrill is gone, burnout descends, and we start looking for something new to relight the fires of passion, or else begin casting blame for our unhappiness.
The end of the cycle can get ugly in all kinds of ways. People have affairs, start fights in churches, or jump from job to job, seeking long-term satisfaction at the price of instability and upheaval. (I first learned about this cycle not from the movies, but from a theology professor who had observed the dynamic in some of the more emotion-based expressions of Christianity).
But even if it doesn’t deteriorate into shouting matches, unconscious acquiescence is not the path to peace and happiness. So how do we beat burnout? A few suggestions:
First, plan to bail before you fail. Some things do not require life-long commitment and work better if we plan to step aside at a predetermined time. I did this as a soccer coach. When my kids were done, so was I. Ministry tasks, volunteer roles, hobbies, these and many more, benefit when we recognize the limits of our humanity and plan to move on to new things before passion becomes drudgery.
Second, identify your non-negotiable’s and plan to replenish your energy. Think of marriage. Think of calling, be it ministry, law, medicine, or business. If it is something worth keeping, it is worth the effort to build emotional and spiritual recovery and renewal space into your life to sustain it. God’s gift of Sabbath is part of this, as was the year of Jubilee for Israel, each occurring not so coincidentally every seventh day and seventh year respectively.
Third, develop long-term goals and short-term objectives that move you toward the goal, and then take time off to celebrate when each objective is met. Celebration replenishes energy.
Finally, and most importantly, build your life and learn to draw your strength, day by day and year by year, on the only one with an infinite supply of energy and passion: Jesus Christ, the same yesterday, today, and forever.
