One line is enough
The best daily reminder is short. A sentence, at most two. It does not explain, does not motivate, does not list tasks. It points — and then it leaves.
"You have 2,748 weeks left. Make today count." That is the whole job. The number does the work; the second clause is permission.
Write your own
Generic reminders get ignored in a week. The ones that land are personal: a line your grandfather said, a promise you made yourself on a hard morning, a question you are avoiding. The grid tells you the time; the reminder tells you what to do with it.
Pause it when you need to. The Stoics never insisted on relentless exposure — only on not forgetting altogether. A reminder you turn off for a season and then turn back on is doing its job better than one you have trained yourself to swipe past.
