Why Working Longer Often Leads to Getting Less Done

It seems logical that if you want to accomplish more, you should work longer. More hours should equal more output, right?

Interestingly enough, at least for me, I’ve often experienced the opposite.

There have been times when I spend an entire day “working,” yet at the end of it, I struggle to point to anything truly meaningful that got finished. Meanwhile, on another day when I only had a short window before a meeting or a flight, I somehow knocked out a task that had been sitting on my to-do list for days.

Why does this happen? As it turns out, there’s a concept known as Parkinson’s Law that offers answers.

Parkinson’s Law

Parkinson’s Law was first stated by naval historian C. Northcote Parkinson in 1955. He hypothesized:

• Work expands so as to fill the time available for its completion.
• The number of workers within public administration tends to grow, regardless of the amount of work to be done.

Put another way, the amount of time we give a task often determines how long it takes.

When our calendar is wide open, the work tends to stretch. We reread emails. We polish things that don’t really need polishing. We bounce between small tasks that feel productive but don’t create much value. The day fills up, but the important work moves slowly.

The Trap of Constant Busyness

Many modern workdays resemble a series of interruptions rather than periods of real progress.

A quick glance at our email. A few text messages. A meeting that could have been shorter, or maybe didn’t need to happen at all.

By the end of the day, you’ve been busy the entire time. But deep, meaningful work rarely happens in fragments.

This kind of work pattern is exhausting because your brain is constantly shifting gears. It’s also inefficient, because complex thinking requires sustained attention.

A Different Model for Working

As it turns out, nature offers an interesting contrast. Many predators spend a large portion of their day resting. They conserve energy until the moment it’s needed.

When the time comes to hunt, however, the effort is intense and focused. Then it’s over. They recover, and the cycle repeats.

For knowledge work, this rhythm makes a lot of sense. Instead of spreading effort thinly across the entire day, concentrate it into shorter periods of full attention.

Pick one important task. Set aside a defined block of time. During that window, eliminate distractions and focus completely on the work in front of you.

When the block ends, step away for a few minutes. Take a walk. Stretch. Grab some water or coffee. Then return and do another focused session.

Focus Beats Time

So, as it relates to personal productivity, it’s my belief that what most people need isn’t more hours. They need more intentional focus during the hours they already have.

When time is limited, the mind becomes selective. You instinctively zero in on the parts of the task that actually matter.

When time feels unlimited, it’s easier to drift into lower-value activities.

This is why some of the most productive people I know guard their time carefully. They schedule periods for concentrated work and protect them. Not because they want to work more. But because they want the work that matters to actually get done.

Eliminating the Work That Doesn’t Matter

Lean thinking teaches us to identify and remove waste from a process. The same idea applies to how we manage our time.

Some of the biggest gains in productivity come from stepping back and asking a few simple questions:

• What work truly creates value?
• What tasks can be simplified?
• What activities could be eliminated entirely?

Many times, the answer isn’t to speed up. It’s to stop doing things that don’t add value. Put into lean lingo…eliminate the muda!

A Better Rhythm

So, in summary, instead of trying to maintain steady effort from morning to evening, I’d encourage you to experiment with a different rhythm.

Try short bursts of concentrated work followed by real recovery. Then another focused sprint. There are many productivity systems, like the Pomodoro Technique (25 minutes of focused work followed by a 5-minute break), that work well.

This pattern, intense attention paired with breaks, may just produce better thinking, better decisions, and better results.

In the end, productivity isn’t about how long you sit at your desk. It’s about how effectively you use the moments when you’re truly focused.
