Some specific notes are things we need to be reminded from time to time.
”Be kind” is a perfect example. We all know it’s a good idea, we all agree on it yet we forget it from time to time.
When we’re drowning we forget it and start being an asshole again.

That note, and many other ones, shouldn’t be notes, nor reminders in our phones. They should be words we recall frequently, like moves in a game, so that we don’t forget them.
