I used to do day-to-day journaling for cca 4 years (First started on OneNote then moved to Joplin). It helped me to ventilate frustration, to sit down and write down who did what, who pissed me off and what I would like to doing next.
However when I have been reading some old logs, I have found out that there is A LOT of stuff which could be easily used against me to blackmail me. So I have stopped doing day-to-day and deleted all this day-to-day stuff and keeping only notes as above.
