PromptSharp Daily · free web issue · #109Prompt of the day
September 25, 2026 · the free cross-vertical sampler: get better at AI and prompting, and see the sharpest prompts from across the network. Today's comes from Focus & Productivity.
The overwhelm reset: cut a bloated list down to what today can actually hold
The list has thirty items and today has room for five. Get an honest cut — what fits, what waits, and what you can stop pretending you'll do.
You are a ruthless-but-kind prioritization coach. I will paste my current task list and how much real working time I have today. Produce: A) CAPACITY MATH — my stated available hours minus meetings and a realistic overhead percentage, giving the honest number of focused hours left, shown as a calculation. B) THE CUT — the tasks that fit today's capacity ranked by impact, and everything below the line explicitly moved to a named later slot (tomorrow, this week, someday, or dropped). C) SUNK-LIST AUDIT — the items that have been carried for two-plus days; for each, a direct call: do it now, schedule it hard, or drop it honestly. D) ONE SENTENCE — what today is actually about, so the rest can wait without guilt. Inputs: [PASTE THE FULL LIST] · [HOURS AVAILABLE TODAY] · [MEETINGS TODAY] · [ITEMS THAT HAVE BEEN LINGERING] Rules: Do not invent capacity that is not there — if the list cannot fit, say so plainly and show the math. Do not soften the cut into "try to fit everything". Verify the kept tasks sum to less than the available focused hours. This is a productivity tool, not medical, psychological, or ADHD-treatment advice. Do not include confidential work details or personal identifiers.
Why it works — Bloated lists lie about capacity, so everything feels behind and nothing gets a clean start. Doing the capacity math out loud and forcing every below-the-line item into a named later slot is what turns a guilt-inducing backlog into a finishable day — the sunk-list audit kills the tasks that were never really going to happen.
Use AI today — a workflow to steal
Summarize a long email thread into what you actually owe
Long threads bury the ask. This surfaces your one action and gets you 80% of the reply written.
Paste the thread and ask: 'Summarize this in 4 bullets, tell me exactly what I'm being asked for, and draft a reply I can edit.'
- Paste the whole thread.
- Ask for summary + 'what do I owe' + draft reply.
- Edit and send.
Sharpen it: For anything you'll act on, ask 'what did you assume, and what would change your answer if it were wrong?' It surfaces the confident-but-wrong risk in 10 seconds.
