This is a great idea! I keep a personal journal, in which I also write about work but not to this level of details.
What I do is to have a repository with experiments and other documentation. For example, when I try new programming languages or libraries, I put it there. When I learn new commands or tricks with commands, I put it there. I sometimes just straight write some documentation about something I did or learn and put it in the repository.
The repository is then highly searchable, and it has been vital for my work life. I’ve been keeping it since school times, so it’s well over a decade old.
I think that the fact I keep voice audio muted helps me not to get to much toxicity D:
