You will now be subject to the whims of a timer in the future. If that's not exhausting for you, go for it.
I can also cancel it just as easily, if it's exhausting. Which--I'm finding it hard to understand why it would be.
I don't schedule my life like that at all, I kinda wander around all day. But the idea of a reminder that I specifically asked for? It's the only kind of reminder I want, actually. It'll keep me from the actually-exhausting habit of checking my watch or wondering how long it's been.
There are days when I walk in and immediately nope-out after a couple of minutes, and that's usually a sign that I'm getting sick.
But when it stops feeling good that's the time to leave, or stop for the evening.
