You blocked the time and sat down. An hour later you were in your email, in Slack or on your phone. You were busy all day, and in the evening nothing tangible was done.

That isn’t a character defect. Your block broke at a specific point. Here you’ll find the four points where deep work breaks, how to spot yours, and the one fix for each.

The step-by-step routine for one focused work block:

Is it a discipline problem?

No. If this sounds familiar, discipline isn’t what’s missing. What you lack is a process for a single block.

Long days at your desk take discipline, and they still don’t give you focus. Discipline and focus are different things.

Tools that run on willpower don’t change that. Pomodoro helped me sometimes, but starting still took willpower. My GTD lists kept growing and put me off more than they helped.

Trying harder doesn’t close that gap. A fixed sequence for one block does.

Where does your deep work break?

If discipline isn’t the problem, the question is where your block fails. The cause depends on that moment, so check it before you change anything.

Where it breaksWhat you noticeLikely causeWhat to do
Before you startSame sentence three times, reaching for the phoneYou’re not fit for focusShorter block, move, nap or postpone
At the startTidying, emails, “quick research” instead of the taskTask unclear or too bigWrite the block goal and next step
During the blockPhone, tabs, daydreams pull you outOpen channels, unparked thoughtsPhone out, apps closed, thought sheet
Over the dayGood morning, nothing works by afternoonUnrealistic benchmark, no real breaksFewer, better blocks with real breaks

Several rows can apply. Start with the earliest one; the next sections follow the same order.

You sit down tired

The earliest point is before the block even starts. If you aren’t rested and awake, no block works, and pushing through only produces work you’ll have to redo.

Being rested is the prerequisite for every step. Before every block, ask yourself honestly whether you’re awake and can think clearly. The answer decides the block:

  • Fit: 45 or 90 minutes, full power.
  • Not quite fit: a shorter block, or activate your body first.
  • Massively tired: a power nap of 10–20 minutes, or postpone the block.

Learn your warning signs. You read the same sentence three times or keep reaching for your phone. Or you feel a pulling sensation behind your eyes.

Once you know them, you can decide honestly before you waste 45 minutes.

Pushing through has a second cost. A block that feels like torture teaches your brain that deep work is unpleasant. Then your brain fights you the next time.

You can’t get started

Say you’re awake and the block still doesn’t begin. Then it breaks at the start: you avoid tasks that are unclear or too big. A written block goal, a small next step and a timer with an end make the start small enough.

A task that isn’t broken down feels impossible to start, so you drift into tidying, emails or quick research. That avoidance can come from dread, so don’t wait to feel better.

Make the start smaller with the same five steps every block. Write the goals on your protocol sheet, the sheet for your block goals:

  1. Set the timer.
  2. Write the end goal as a finished state: “Article is published”, not “Write article”.
  3. Write the block goal for this block, such as “First draft of the outline is done”.
  4. Write the next action if it isn’t obvious: the smallest step you can take right now.
  5. Start.

The timer tells your brain the work has an end, which makes starting easier, especially with unpleasant tasks. When in doubt, start with 15 or 25 minutes; you can always go over.

Before you stop for the day, note what you want to start with tomorrow. Then you sit down in the morning and begin without deliberating.

You can’t stay in it

Once you’ve started, the next point is staying in. Three things pull you out of a block: your phone, open apps and tabs, and your own thoughts. Each needs its own fix.

  • Phone: switch it off and put it in another room. Airplane mode on your desk isn’t enough; it has to be out of sight.
  • Apps and tabs: close everything you don’t need, usually the programs from your previous task.
  • Your thoughts: park them on a thought sheet, a second blank sheet next to your protocol sheet. Then return to the task.

Switching itself has a cost, too. Sophie Leroy called it attention residue (Why Is It So Hard to Do My Work?, 2009). When you leave an unfinished task, part of your attention stays with it and performance on the next task drops.

Then there are your own thoughts: once the distractions are gone, your mind may start to wander. Thoughts keep coming back because your brain is afraid of forgetting them. The fix is Thought Parking: catch the thought, write a keyword on the thought sheet, check your protocol sheet, continue.

Once the thought is on paper, your brain knows it won’t get lost, and it calms down. Catching yourself drifting takes practice and gets easier with every block.

If you lose track of the task completely, write the next mini step on the protocol sheet. Thinking about it brings you back.

You can’t keep it up

Even when single blocks work, the day can still fall apart. If you measure yourself against eight focused hours and skip real breaks, you’ll crash. A few good blocks a day is the realistic target.

For highly concentrated work, four to six hours a day is a realistic upper limit. Eight is unrealistic and costs you the next day.

On good days I manage five to six hours, spread across several blocks of different length. On weak days it’s three, and that’s fine.

The four-hour figure goes back to a review of deliberate practice by Ericsson, Krampe and Tesch-Römer (Psychological Review, 1993). Older training studies cited there found essentially no benefit beyond about four hours of practice a day.

They measured skill practice, not knowledge work. So it supports a limit of a few hours, but no exact number for your desk work.

Long days don’t fix a crashing afternoon either: a twelve-hour day can hold only a few hours of real work. Take real breaks instead: move your body, no phone, no messages. And stop for the day when the quality of your blocks drops, even if it’s only been three hours.

After a failed block

A failed block tells you where your process needs work. It doesn’t show that deep work isn’t for you. Beating yourself up doesn’t help your next block.

At the end of each block, check against your block goal: reached, partially, not at all. Don’t judge, just observe. Not reaching it tells you something for the next block.

Bad days happen, even with a good process. After a bad night, it doesn’t run perfectly. But it still works, just with fewer blocks.

Start with one block, not your whole day

The four sections above are the phases of one block, so the fix belongs in the block:

  • Before: you sit down tired.
  • Start: you can’t get started.
  • During: you can’t stay in it.
  • Stop, break, repeat: you can’t keep it up.

So don’t overhaul your day. Approaches that start with your whole life, your whole day or your whole task list aim too big. Start with the smallest unit: one block of focused work.

Your first blocks won’t be perfect. You’ll forget steps and get distracted anyway; that’s normal.

So pick your row from the table above and change only that in your next block. Repeat that block until the fix holds.

Once one fix holds, the next step is stacking your blocks. A few good blocks with real breaks in between turn a busy day into a day with results.

FAQ

Is it normal to find deep work hard?

Yes, finding deep work hard is normal, especially in your first blocks. You’ll forget steps and get distracted anyway; everyone starts that way. Catching yourself drifting is a skill, and it gets easier with every block you do.

How long does it take until deep work gets easier?

No reliable study gives a fixed timeline for deep work, so be wary of exact promises. With the process from my book, the steps become routine after a few weeks, and you stop thinking about them.

Could ADHD be the reason I struggle with deep work?

ADHD can be one reason you struggle with deep work, but no article can tell. If focus problems are lifelong and show up everywhere, not just at your desk, get them assessed professionally. The fixes here apply either way.

Can I do deep work if my job expects instant replies?

Yes, deep work at a job with instant replies is possible in smaller units: start with one protected block. Tell the people who contact you regularly when you’re unreachable. That also removes the lingering expectation that a message is about to come in.
