March of 2020 seems a very long time ago. The coronavirus pandemic was roaring to life in the US, and it had arrived in Cambridge, Massachusetts where I lived and worked. I was leading an international team of editors, half of whom worked in the Cell Press office in Cambridge near the MIT campus.

I do apologize for this dull cliche, but I know I'm right about this: change is hard. I don't mean that it's hard to adapt after someone or something forces a change on you. That's true too, but it's not my topic here. I'm talking about this: you want to change, or you need to change, or both. You know what the change has to be. Maybe you know what the first step has to be. It's change, and it's hard.
