I have had long stretches of sadness in my life. Not depression, mind you. I dipped an oar in that black river at the end of my annus horribilis; I learned the difference. Sadness is not intractable. It will seem odd to hear this, but I cherish my sadness. I do not revel in it, nor do I valorize it, but when it comes, as it must, I do not turn away from it as from an unwelcome guest. There are good reasons to feel sad. This past year has laid a few at my feet. I have made decisions that would, at some point, along with a bounty of other emotions, cause me sadness.
Sadness passes. So does happiness. I am happy by default. I have a sleep app that prompts me to reflect on how I feel at the end of the day. I almost always designate “happy,” even on days that I also tag as stressful. Even on days when I have felt sad at some point during the day. However, I do not feel happy exclusively, nor do I adamantly cling to that emotion.
When I grew up, my mother warned my brothers and me away from things that would make us feel sad. She policed movies and television shows that grappled with serious and discomforting issues like nuclear war or actual (not fictional) crime. The ugliness never plagued me as much as the shutting off of truth did. Information—truth—drew me with powerful magnetism. Even now after watching the news of the day, I can let anger and sadness pass even as the information remains. There are rare occasions when the cacophony of information drowns out other, happier possibilities. There are times when the information mixes with personal challenges and setbacks. The personal is harder to overcome.
I fortify my day with opportunities for joy. I surround myself with students—people who are younger than I am. They have avoided the cynicism that adults wear too willingly. I go to the gym and lift weights, then charge ahead on the elliptical for 23 hard minutes (530 calories burned!). This summer, I took my place at the table in the school library and worked at my book. I go home, cook dinner (steak, broccoli, and brown rice with avocado), then read. I head to bed at a reasonable hour.
Sometimes, happiness—extreme happiness—is necessary. The first big push for a new writing project requires a kind of ignorant and unabated bliss. There are 100,000 words ahead, and no one may ever read them, but I am going to write them anyway. I began this past book in the bountiful throes of such exuberance. Boundless joy carried me into the first hundred pages of my book. Fortunately, when the cause for that joy left my life, the writing continued. I was writing—at last!—and that became the source of joy for me.

Even now, writing this, I feel happy. I look at a photograph from a year ago: the doctor on horseback. I am ecstatic. The novel had not yet begun. As far as the horse carried me, the novel carried me farther—and further. It helps to know the difference.
When I was depressed in 2002, I sought out a counselor, and he advised me that happiness was, if not an illusion, then, at least, a particularly difficult aim. He made this suggestion because I was tangled up in feeling that I was mistaken for not being able to feel happy. My relationship of the past 6 years had ended. I was teaching in a strange place, and my friends were hundreds of miles away. My mother had just gone through a harrowing battle with cancer. My father had just died. Happiness was, at best, elusive. And, perhaps most damning of all, I was not writing.
Writing is difficult—for the reasons I pointed toward above, but also because it requires a kind of vulnerability. One must, at once, care and not care at all about the reader. One must care, and not care at all, about the outcome of the effort. One must learn to love the process above all. This is true of life as well, but writing lays this truth bare in ways that many other kinds of work do not. It is work, and it is, absolutely, not.
No matter what other happiness—even joy—passes from my life, this more vulnerable happiness remains. It was always there, waiting for me to find it, perhaps waiting for me to need it. Finding it, and needing it, I am vulnerable now—open to a more profound sadness—but also open to a deeper joy. I write and proceed.
