# How to Improve Productivity at Work: A Researcher's Cut URL: https://aginsi.com/journal/how-to-improve-productivity-at-work Type: blog Locale: en Published: 2026-10-15 Updated: 2026-10-15 --- > Practical ways to improve productivity at work: guard your focus hours, cap priorities at three, read once and keep meeting notes to decisions, with the evidence behind each. How to improve productivity at work comes down to one shift: stop trying to do more and start protecting the few hours where real thinking happens. Cut the switches between tasks, decide your three priorities before you open your inbox, and process what you read and hear once instead of three times. Most of the gain comes from subtraction. The rest of this piece explains why that works, what the research does and does not say, and which small habits survived our testing. ## Why most advice on how to improve productivity at work fails Open any ranking page on this topic and you find the same twenty tips. Wake earlier. Batch your email. Try a new app. Each one is defensible on its own, and together they form a to-do list about your to-do list. The problem is not a shortage of tips. It is that they all treat your day as a supply of hours to be filled. Knowledge work does not behave that way. The scarce resource is attention, and attention has a rhythm: it peaks, it drops, it recovers. A plan that ignores the rhythm will lose to it every afternoon around three. Gloria Mark, who has studied workers in the field for nearly two decades, reports that attention on any one screen [averages about 47 seconds](https://gloriamark.com/attention-span/). Her book also pushes back on a popular idea: that you should be in unbroken flow all day and feel guilty when you are not. Her argument is that we cannot hold sustained focus indefinitely, any more than we can lift weights nonstop. Productivity, on her account, is about matching hard work to the hours when you can do it. That reframing is the foundation for everything below. If focus is a limited, rhythmic resource, the job is to spend it on purpose. ![A blank notebook with three hand-drawn circles beside a pencil and a small timer](https://fdzlnqpwsaniezitwiuw.supabase.co/storage/v1/object/public/cms-media/aginsi/2026-10/1c1286-i1.webp) ## Is multitasking really costing you 40 percent of your day? You will see the 40 percent figure everywhere, usually stripped of context. Here is the original claim, from the American Psychological Association's summary of task-switching research: [even brief mental blocks created by shifting between tasks can cost as much as 40 percent of someone's productive time](https://www.apa.org/topics/research/multitasking). The key words are "as much as". The same page is more careful than the people quoting it. Each individual switch may cost only a few tenths of a second. The damage comes from repetition. Switching also costs more when the tasks are complex and when the task you are returning to is unfamiliar. So the honest reading is this. Do not treat 40 percent as your personal loss. Treat it as a ceiling that shows up when you alternate constantly between demanding tasks. A reviewer who flips between a long report, a chat thread and a spreadsheet every few minutes sits near that ceiling. Someone who reads for an hour, then answers messages for twenty minutes, sits far from it. The practical rule that follows: group similar work, and put a wall between hard tasks and messages. Close the chat client during the hard block. Leave your phone in another room, or at least face down. This is dull advice, and it is the advice with the best evidence behind it. ## What should you decide before you open your inbox? Skip the elaborate planning system. What works is a single decision, made before anything else reaches you: which three things would make today a good day? Write them on paper. Three, not seven. If a fourth item feels urgent, it either replaces one of the three or waits. The number matters because it forces a ranking, and ranking is the part people avoid. A few observations on how to make this stick: - Write the three priorities the evening before, when you still remember what is blocked. - Phrase each as an outcome you could check ("send the methods section to the co-author"), not an activity ("work on paper"). - Put the hardest one first and attach a time to it. An item without a time slot is a wish. An inbox is someone else's to-do list. Opening it first hands your morning to other people's priorities. Open it at a set hour instead, once your first block is done. ## How much of your day is actually reading and listening? Here is the part generic productivity advice skips. For researchers, analysts, journalists and consultants, a large share of the working day is intake: reports, papers, threads, newsletters, meeting talk. Time management advice treats intake as free. It is not. Count it for one week. Note how many hours go to reading, how many to meetings, and how many to writing something new. Many people find the creative output is the smallest slice, and that the intake slice is the one they never examined. The useful question is not "how do I read more?" but "which of this intake changes a decision or a sentence I will write?" Most of it does not. The goal is to sort before you read, and to read the passages that matter closely. ![A quiet meeting room table with a notebook and laptop after the meeting ended](https://fdzlnqpwsaniezitwiuw.supabase.co/storage/v1/object/public/cms-media/aginsi/2026-10/cea898-i2.webp) If reading is your biggest block, our piece on [how to read faster](/journal/how-to-read-faster) covers the sorting step in detail. In short: triage first, then read the two or three sources that deserve it, then stop. ## Reading once: a method that survives a heavy week The biggest hidden cost in knowledge work is rereading. You read an article on Monday, remember only that it was good, and open it again on Thursday to find the one number you needed. That is the same intake paid for twice. The fix is to leave a trace the first time. Highlight less than you think you should, and write a one-line note in your own words next to each highlight. Highlighting is choosing. If you cannot say in a sentence why a passage matters, it does not need saving. Tools can carry part of this load. A read-it-later app that keeps your highlights searchable beats a folder of forgotten PDFs. We have used Readwise Reader for this: it takes PDFs, newsletters and web articles into one place and treats highlighting as the main act rather than an afterthought. Skip it if you read mostly on paper and are happy with that. A tool does not fix a habit you do not have. Worth trying if you notice that your best sources are scattered across tabs, emails and downloads folders. ## Do meetings need notes, or do they need decisions? Meetings are the second large intake block, and the one with the worst return on attention. Two questions cut most of the waste. Does this meeting need me? And what will exist afterwards that did not exist before? If the answer to the second is "nothing", decline or ask for a written update. If you do attend, write down decisions and owners rather than a transcript of what was said. We cover the mechanics in [how to take better meeting notes](/journal/how-to-take-better-meeting-notes). An AI notepad can help when your calendar is back to back, because you can stay in the conversation instead of typing through it. Granola is the one we would point to here: it listens on your device, so no bot joins the call, and it merges your own jotted lines with the transcript. As listed in October 2026, the free tier covers unlimited notes with a capped history, and the Business plan is $14 per user per month. Be honest about the limit. A summary is only as good as the meeting. If nobody stated a decision aloud, no tool will invent one, and you should not trust a summary that sounds more certain than the conversation was. Read the output against your own jotted lines before you forward it. ![Hands highlighting a printed page with margin notes in pencil](https://fdzlnqpwsaniezitwiuw.supabase.co/storage/v1/object/public/cms-media/aginsi/2026-10/00d189-i3.webp) ## Where should your notes live so you find them again? A note you cannot find is a note you did not take. Most people lose time not on writing notes but on retrieving them, across three apps, a notebook and an email draft folder. Pick one home. It matters less which. What matters is that every highlight, meeting decision and half-formed idea ends up in the same searchable place within a day. Two honest options for different temperaments. Obsidian stores plain Markdown files on your own machine, so your notes outlive any company and any subscription. The app is free; the optional Sync plan was listed at $4 a month billed annually. Notion suits a team that wants notes, tasks and wikis in one shared workspace, and it handles structured databases well. The trade-off is that it asks more of you to set up, and a workspace built in a hurry becomes its own source of clutter. Our view: for a solo researcher or consultant, plain files and a good search beat an elaborate system. For a team, a shared workspace wins because the alternative is five private ones. In both cases, spend an afternoon setting it up and then leave it alone. Tool-hopping is procrastination with better branding. ## Which popular productivity habits should you skip? Some advice is repeated because it feels productive to follow, not because it works. - **Inbox zero as a goal.** An empty inbox is a side effect of good triage, not a target. Chasing it turns into another way of being busy. - **Waking at five.** If your best focus comes mid-morning, an earlier alarm only makes you tired during it. Find your peak and defend that. - **Color-coded everything.** If the system takes longer to maintain than the work it organizes, drop it. - **Constant app switching in search of the perfect tool.** Each new tool carries a setup cost and a learning curve. Change tools only when the current one fails at a specific, named job. None of these is harmful in moderation. They fail when they replace the harder decisions: what to drop, what to protect, what to say no to. ## What we would actually do this week Here is a short sequence, in order, that you can run without buying anything. - Track one day of intake. Write down every hour that went to reading, meetings and messages. - Choose one daily focus block of 60 to 90 minutes, at the time you think best, and guard it. - Write three priorities on paper the evening before, each phrased as a checkable outcome. - Group messages into two fixed windows. Close the chat client outside them. - Pick one place for notes and move everything there. - At the end of the week, count what you did not have to reread. Do this for two weeks before you evaluate any tool. If after two weeks reading and meeting intake is still your bottleneck, that is the moment an AI summarizer or notepad earns a place, because by then you know exactly which job you are hiring it for. The observation we keep returning to: productivity at work is mostly a sorting problem. Which tasks, which sources, which meetings deserve your best hours? Everything else can be shorter, later, or not at all. What is the one thing you would stop doing on Monday if no one would notice? ## FAQ ### What is the fastest way to improve productivity at work? Cut task switching. Group similar work, close chat during your hardest block, and pick three priorities before you open your inbox. These changes cost nothing and remove the most common source of lost time. ### Does multitasking really reduce productivity? For complex tasks, yes. The American Psychological Association summarises research showing that brief mental blocks from switching can cost as much as 40 percent of productive time. Each switch is small, but repeated switching adds up. ### How many priorities should I set each day? Three. A short list forces you to rank, which is the step most people avoid. Phrase each as an outcome you can check, and give the hardest one a fixed time slot. ### How long can a person stay focused at work? Not indefinitely. Gloria Mark's field research reports attention averaging about 47 seconds on any one screen, and she argues we should follow our own attention rhythms rather than chase unbroken flow. ### Do AI note-taking and reading tools improve productivity? They can, for a specific job such as capturing meeting decisions or keeping highlights searchable. They do not fix an unclear priority or a meeting without decisions. Try the habits first, then add a tool. ### Is inbox zero worth chasing? Not as a goal. An empty inbox is a by-product of good triage. Open email at set hours after your first focus block and sort by what changes a decision.
