Assignment: Write 15+ minutes per day. Subject matter is up to you. I just want to get you more comfortable with writing.
You can do private journaling, you can write thoughts on intellectual issues, you can write todo lists to organize your days, you can write commentary on TV and YouTube, you can write suggestions for your workplace (no need to tell your workplace), you can write notes on things you learned, you can write explanations of how to do things, whatever.
Try not to skip more than 1 or 2 days per week. Keep track of what days you write on and maybe time and word count. But don’t try to make your time or word count go up; big numbers aren’t the goal here.
Share a write every week or two. It’s fine if most of it is private but try to write something shareable sometimes. You can share more if you want to.
Also I think you were or are doing something like this already. Let me know what you’ve been doing and how it’s been going.
