Some people feel Covid is behind us, some are still being cautious about in-person meetups. Whatever your preference, it's also sweet to have the freedom of online connections when you're a writer. Or maybe you're a new parent or travel a lot for work, and you can't imagine a schedule where you can meet physically with other writers. Such is our life now, or so it is for many of us.
If you're working on a book, as I've said often in these posts, you need ongoing support. It's very challenging to write, develop, and submit a book in isolation. It speeds and smooths the way if you have fellow book writers creating a community and lending their enthusiasm.
When I poll student in my online classes, at least half the group belongs to a writer's group or has a writing partner. Writing is solitary; it's easy to get a little nutso when you've been on your laptop, deep in your story, for hours without interacting with another human. I know this well! Even virtual interaction with someone else who gets it can ease your way back into your normal life. Fellow book writers also give needed perspective on what you've been doing (even if it's a universe in itself). And of course, there's the immense value of feedback along the way.
