Based on a Slack discussion at work, about creating a job roadmap (à la https://roadmap.sh/roadmaps) I thought to myself:
Why not have a personal roadmap/changelog to document the things I've worked on, instead of something like a journal?
I did a Google search for "personal changelog" and found a blog post by @brian Lovin where he described his process for doing just that, and how it led him to Polywork. That sent me to Twitter where I found a tweet by @claravanstaden offering an invite code.
Now here I am. I love the Internet :)
