How to get more done without working longer

1. How to get more done without working longer

Stop adding hours and start subtracting tasks. What's at work here is the 80/20 law, also known as the Pareto principle: roughly 20% of what you do gives 80% of the result. The rest eats your time and changes almost nothing — while feeling exactly like work.

You can test it on yourself in five minutes. Every Monday, write out everything you have to do that week, including the small and unpleasant bits. Then ask yourself one honest question: which two or three of these will actually move things forward? Not which ones are important — nearly everything looks important — but which ones move the needle.

In practice it looks like this. Eighteen items on the list: reply to emails, clear out the Downloads folder, update your portfolio, arrange a meeting with a client, buy a printer cartridge, reread a contract, and fourteen more of the same. Two of them move things: the meeting and the portfolio. Everything else can wait a week and nothing will happen — it only looks urgent because it's sitting in the list.

The hard part of 80/20 isn't spotting those two items. It's admitting the other sixteen are noise. They create the feeling of being busy without any progress, and that's precisely why we reach for them first: they're clear, quick and hand you a small satisfying tick. The big important thing hands you nothing for months.

2. How many tasks to plan for one day

Three — and only one of them big. Not five, not ten, and definitely not fifteen. Two small ones and one serious one is the amount that genuinely closes in a day that also contains phone calls, children, queues and bad weather.

The reason isn't laziness. We systematically underestimate how long things take, by 1.5–2 times — a stubborn effect known as the planning fallacy. "Make the presentation" takes forty minutes in your head and two hours in reality: you have to dig out the numbers, redo the slide that wouldn't fit, read it through, fix a typo. The same applies to every line of the list. Fifteen items at forty minutes each in your head is ten hours in the real world.

That's why a list of fifteen items demotivates you before the day has even started: you look at it in the morning already knowing you'll lose. And in the evening, even after finishing six things, you feel like you failed — because nine are still there. Three out of three gives you the exact opposite feeling for what may well have been the same amount of work.

One practical trick: name the one big task of the day first, then add the two small ones. Do it the other way round and the big one never fits — small tasks will always find a way to fill the day.

3. What to do when there's more to do than there is time

Instead of asking "how do I squeeze it all in", ask yourself a different question: "what am I giving up". That isn't a turn of phrase, it's a working substitution. The first question has no answer; the second one always does.

A to-do list is endless by definition. It fills up faster than you clear it, and it always will — that's a property of lists, not evidence that you're badly organised. Which means "getting everything done" is an unreachable goal, and every day spent chasing it ends in a loss by default.

The mechanics are simple. Take the three most important things for today and deliberately cross out the third. Don't quietly shunt it to tomorrow — say it out loud: I'm not doing this one this week. Deliberately dropping the third most important thing frees up energy for the first, and the first finally moves, instead of all three standing still, spread across the day in a thin layer.

Dropping something feels like defeat exactly once. After that you notice it is the planning: a plan with nothing crossed out isn't a plan, it's a list of wishes.

4. When to group similar tasks

Whenever they need the same mode of thinking. All the calls back to back. All the email twice a day. All the payments in one go. All the shopping on one route, rather than five separate stops on the way home.

The reason is arithmetic: every switch between types of work costs you up to 20 minutes to get your concentration back. If you jumped from writing to a call and back six times today, that's two hours you never noticed losing — they don't look like wasted time, because you were doing something the whole while.

Group by mode, not by topic. "Call mum" and "call the repair shop" are unrelated topics but the same mode: talking. "Write to the client" and "write the post" are also one mode, even though the jobs have nothing in common. Meanwhile "write an email" and "make a call" don't belong next to each other, even though both are communication.

There's a limit, too. Two big creative tasks back to back don't batch — that's not batching, that's four hours of demanding work after which there's nothing left of you. Batching earns its keep on routine, where the switch costs more than the task itself.

5. How to stop losing time on small stuff

Small jobs stretch to fill exactly the time you give them. That's Parkinson's law, and it never misses: a reply you could write in three minutes will take half an hour if half an hour is available.

The antidote is capping the frame. Set a timer for 25 minutes and give all the small stuff one block together: the email, the call to the bank, the doctor's appointment, the transfer, the order. When the whole batch has 25 minutes, each job shrinks to its real size, because there's simply no room left for dithering.

The alternative is smearing those same five small things across the day. It looks harmless, but it's five exits from your work and five returns, each one charging you attention. That's exactly how a day in which you were apparently busy throughout ends with nothing finished.

Whatever doesn't fit into the 25 minutes isn't a disaster: it moves into tomorrow's identical block. If it fails to fit three days running, though, it isn't small stuff any more, and it needs planning separately, like a proper task.

6. Does multitasking help you get more done

No, it's an illusion — and the most expensive one going. The brain doesn't do two things at once: it switches quickly between them and loses time at every transition. The point here isn't the quality of the work but the sheer volume of it: multitasking mode takes more hours to produce the same number of finished things.

Do the sum on a simple example. Three tasks of forty minutes each, done one after another, is two hours. The same three tasks "in parallel", hopping every ten minutes, is those same two hours of actual work plus a dozen transitions, each one dragging a "where was I" behind it. Call it nearly three. The output is identical.

The second sum is mistakes. In multitasking mode there are more of them: the wrong figure, the wrong name in an email, a line left out. Every one of those comes back as rework, and rework is a straight deduction from how much you got done. So the feeling of "I'm handling several things at once" almost always means "I'll be doing them twice".

There is one honest exception: multitasking works when one of the jobs needs no attention at all. The washing machine runs while you work; the soup simmers while you're on the phone. Anything with the word "think" in it doesn't qualify.
