Love songs use words like “always” and “forever” but indefinitely is all we get.

I always want to think that Robyn and I will be married and love each other always and forever. Including in the afterlife, and all through whatever comes next, until there is no more next left to have. I want to believe this, even though we really don’t have any say in the matter.

Living for indefinitely is a bit of a paradox. Because you have to plan for forever, not knowing whether you’ll make it past next week. And so much can happen between now and next week - I could be vaporized by a laser, eaten by a dinosaur, or drowned in a pool of chocolate pudding, or undergo one of many more conventional methods of death. We could do something so cruel to each other that our marriage dissolves. The universe might must...stop. We don’t really know, because nothing is definite.

I always have thought of the phrase, “live like there are 10,000 tomorrows all of which that may never come” as a paradox that fits when contemplating how to live a life.

But how? How do we prepare for a life, marriage, and maybe and afterlife together that lasts indefinitely. How do we prepare for anything that is indefinite?

All I can think of is a two principles: make adjustments and manage exponential growth.

Making adjustments to me, is all about the process of realizing our marriage is imperfect and trying to change the underlying behaviors which lead to fissures. To me there’s certainly a process for managing these fissures (we use temperature check, for example). Certainly things like “communication” and “conflict resolution” are important skills.

But the more important, overlooked factor here I think, is the humility it takes to acknowledge that our marriage needs to be worked on every day. Every interaction we have is a chance to work on our marriage. We cannot take days off. Processes like temperature check don’t work if we don’t humbly believe we actually need to utilize them.

And the principle of managing exponential growth, to me, is the understanding that both good and bad things can snowball quickly and that we should act accordingly.

Of course, it’s obvious that problems in a marriage can spiral out of control quickly. And so, obviously, it’s important to solve problems quickly, before they get big. The old adage of “never go to bed angry” is a good rule of thumb that Robyn and I really believe in.

But exponential growth can also be positive, and we need that reserve of goodwill to carry us through hard times. Just as we can’t let problems spiral out of control, we can’t let opportunities to strengthen our marriage and create joy - even little ones - pass by.. Little things - like writing a little note, or making a special treat, or saying I love you at an unexpected time - these all build on each other to create joy and love.

There are probably hundreds of these tiny little interactions every day, and those opportunities for joy and love can’t be wasted. We need to give positive exponential growth a fighting chance to happen. We can’t wait for grand gestures to grow our love and trust - they’re not enough to help our marriage at least, last indefinitely.

As it happens, the idea of managing exponential growth also is rooted in a mindset of humility. Because by trying to managing exponential growth, we’re acknowledging that negative exponential growth could crush us and that our marriage is not naturally dynamic enough to survive without positive exponential growth, either.

It seems to me, the key to a marriage that lasts indefinitely is to deeply and truly respect the challenge and then act accordingly. For many years I have wondered where that sort of humility comes from. Like why do some people have it and some people don’t? Humility, to me, seems like one of the most important dispositions to have when participating in human relationships.

It’s the subject of deeper reflection, but I think listening and observing the world around us (even the ugly parts) and experiencing real pain and loss are two things that help humility to germinate in a person.
