My go to way of taking notes is sending messages to myself. Previously with Signal’s “Note to self” and now with my own channel with Element. It is fast way of taking notes, but horrible in long run since you cannot group notes or add tags or anything else that you would expect from good note taking tool. I have Nextcloud notes, but I still do it since I am used to it and it is fast way of syncing notes with mobile and PC. Anyone else has interesting ways of keeping notes?
I email my work account because I don’t check work emails when I’m not at work. I once considered creating an automation system for emailing my personal address and having those emails get added to a to-do list, but didn’t ever pull the trigger.
I sms myself information when it’s going to be relevant shortly after, but otherwise my notes live in Simplenote and have for years. It syncs across my devices.
