Change is good. It's been one of my guiding stars. I've written about it here.
Sometimes I've initiated the changes. I've moved several times. I've changed spouses/partners. And sometimes the changes initiate me: I've buried people I love, both older and younger. The finality of losing a person is an ache that is like nothing else.
Change, and all the good things that come from change are accompanied by loss and sadness. They have to be. Change means leaving something behind. Here is something I wrote about the sadness (which is a paraphrased quote from a book I love):
But as I watch things in my life recede in time, I too wish that the psychic umbilicus would snap and whip my sadness down the long corridor to the void of oblivion.
Right now, things are changing in my life, in my science, in the people I work with. That's the nature of what we do. We nurture, we mentor, we help, and when we get to be close or even just friendly, the people with whom we work leave. Or they die. My oldest, bestest, longest collaborator is turning 90.
I started to write that I am better at the sadness now than I was. But its not better. Its just different. I too change.
