@joonikko I keep daily work notes as well: journaling type things for what I've been working on, meeting notes for meetings I take part in and the type of work journal Tanner Christensen talks about here: https://www.tannerchristensen.com/notes/using-a-work-journal-to-create-design-case-studies
I recently read a similar article by Sam Bleckely on what he calls Lab Notebooks: https://sambleckley.com/writing/lab-notebooks.html
I find it so useful to be able to reference back to what was discussed/agreed in meetings, how I solved problems and in general what I've achieved at work.
@joonikko I like how Sam puts it:
"A lab notebook makes it safe to stop work at any time."
Being able to keep track of progress and thoughts while working helps enormously when having to context switch.
