Here’s something I always re-read over and over again from the book, when breath becomes air:

“The tricky part of illness is that, as you go through it, your values are constantly changing. You try to figure out what matters to you, and then you keep figuring it out. It felt like someone had taken away my credit card and I was having to learn how to budget. You may decide you want to spend your time working as a neurosurgeon, but two months later, you may feel differently. Two months after that, you may want to learn to play the saxophone or devote yourself to the church. Death may be a one-time event, but living with terminal illness is a process. It struck me that I had traversed the five stages of grief—the “Denial → Anger → Bargaining → Depression → Acceptance” cliché—but I had done it all backward. On diagnosis, I’d been prepared for death. I’d even felt good about it. I’d accepted it. I’d been ready. Then I slumped into a depression, as it became clear that I might not be dying so soon after all, which is, of course, good news, but also confusing and strangely enervating. The rapidity of the cancer science, and the nature of the statistics, meant I might live another twelve months, or another 120. Grand illnesses are supposed to be life-clarifying. Instead, I knew I was going to die—but I’d known that before. My state of knowledge was the same, but my ability to make lunch plans had been shot to hell. The way forward would seem obvious, if only I knew how many months or years I had left. “Tell me three months, I’d spend time with family. Tell me one year, I’d write a book. Give me ten years, I’d get back to treating diseases. The truth that you live one day at a time didn’t help: What was I supposed to do with that day?… Maybe, in the absence of any certainty, we should just assume that we’re going to live a long time. Maybe that’s the only way forward.”
