The fix is to stop trying to remind yourself on the right day, and instead set a reminder to check whether it's the right day. Set a far-out one-off reminder ("remind me in 3 months to check the passport renewal window") or a loose recurring check-in, and let that future prompt decide if action is needed — rather than trying to pin an exact date today for something that doesn't have one yet.
Why "someday" tasks disappear
These tasks fail differently to normal to-dos. A "buy milk" reminder fails because you ignored it. A "renew passport before it expires" task fails because you never captured it properly in the first place — it lived in your head, or in a note buried under forty other notes, with no trigger to resurface it until the day you're standing at airport security.
The problem isn't memory, it's timing. You know about the task today, but there's no natural cue to bring it back to mind in three months, or next quarter, when it actually becomes actionable. Notes apps are especially bad at this — a note is passive, it waits for you to go looking. If you don't have a reason to open that note, it doesn't matter how well you wrote it.
This is also why vague habit intentions fizzle, per James Clear's Atomic Habits: intentions without a specific time and trigger rarely convert into action. A someday task needs the same thing a habit needs — a concrete future moment where it re-enters your attention, even if that moment isn't the deadline itself.
Two ways to handle it
There are really only two useful structures for a no-date-yet task: a far-out one-off, or a loose recurring check-in. Which one you use depends on how much lead time the task actually needs.
- Far-out one-off, for tasks with a rough but knowable trigger point. If you know the passport expires in nine months and renewal windows open at six months out, you don't need a reminder today — you need one in three months' time, when the task actually becomes relevant. In Nudgle: "remind me in 3 months to check the passport renewal window." Plain English, no date picker, and it sits quietly until the moment it's useful.
- Recurring check-in, for tasks with no clear trigger date at all. "Follow up on that quote next quarter" doesn't have a real deadline — it just needs revisiting periodically until it resolves. A quarterly nudge works better than guessing a date: "remind me every 3 months on the first Monday to check if it's worth following up on the [supplier] quote." If it's still not time, dismiss it and the next check-in arrives on schedule anyway.
The mechanism matters more than the app. What you're building is a cue — BJ Fogg's Tiny Habits framework calls this an "anchor," a reliable trigger that fires at the right moment rather than relying on willpower or memory to resurface the task unprompted. A far-out reminder is just an anchor with a long fuse.
What a good someday-reminder actually says
Three things make these reminders useful when they eventually fire, rather than just another notification you swipe away:
- State the check, not just the topic. "Passport" tells future-you nothing. "Check the passport renewal window — it opens 6 months before expiry" tells you exactly what to do and why now.
- Include the reason it matters. If you wrote "follow up on quote," you'll have forgotten which quote, from whom, and why it was time-sensitive. "Follow up on the roofing quote from Dave — he said prices go up after spring" survives the memory gap.
- Pick an interval slightly ahead of when you'll need it. Give yourself buffer. If the passport window opens at 6 months, set the check-in for 7, not 6 — so a slow week doesn't turn into a missed window.
Where this breaks down
Not every someday task deserves its own reminder. If you're stacking up a dozen far-out one-offs "just in case," you end up back where you started — a wall of notifications you start dismissing without reading, which is the same alarm fatigue that kills fixed-time reminders. Reserve this approach for tasks with real consequences if forgotten (expiring documents, contract renewals, warranty windows), not every vague someday idea.
It's also worth being honest that this only works if you're already checking the channel the reminder arrives in. A reminder that fires in Telegram is only useful if you actually open Telegram — if you've muted the app or don't use it day to day, the far-out reminder just becomes tomorrow's ignored notification. Try Nudgle free if you're already living in Telegram; if you're not, a reminder tool bolted onto an app you don't open won't fix the underlying problem.
One more limitation: fixed far-out reminders lose accuracy if circumstances shift. If your passport situation changes, or the quote deadline moves, the reminder doesn't know that — it just fires on schedule. Treat the notification as a prompt to check current status, not as gospel.
One thing to do today
Pick one thing you've been meaning to deal with "eventually" — a renewal, a follow-up, a decision you're deferring — and set a single reminder for it right now. Not a note, not a mental flag: an actual future trigger, three or six months out, with enough detail that it makes sense when it arrives. That's one fewer thing quietly rotting in the back of your mind.
