I message myself in teams, mainly to store articles, draft messages, and memes for future use. I also email myself draft emails to pick up the next morning.

I have workflow in Alfred that copies the selected text into a ‘notes’ list in Reminders, which is linked to a keyboard shortcut, which is assigned to a spare button on my mouse. At the end of some research task I’ll consolidate it all, and add tags etc.

I spend way too much time stuffing around with similar hacks in obsidian.

I'll admit that I slack myself a lot. As well as rely on reminders to revisit messages at a later (less busy) time.
