I like using Japanese kana in my homework. I'm learning the language, and it helps with calming down after the rage of "what the hell is this thing, that doesn't make any sense???"
As a result, i have to prove that the set ま is open.
I think there might be an objectively true answer for most (all?) here: wake up.
There might be some all nighters, but besides that, every day for almost everyone starts with waking up, which is also arguably an important part of the daily routine.
The cherry stream has all the keys I need, presses feel good, and it just works.
