We’ve all heard the saying: “If you want something done, ask a busy person.”
They get things done because they have limited time.
That’s Parkinson’s Law in action:
Work expands to fill the time you give it.
When time is open-ended, focus leaks and energy fades.
Soon, time starts running you instead of the other way around.
Here’s the nuance: heuristics are helpful, but not universal.
Parkinson’s Law is perfect for functional tasks like clearing email, processing approvals, or planning projects — work that benefits from firm limits. But creative work (including solving complex problems) is different. Ideas often need space to connect.
In short: functional tasks thrive on limits; creative tasks thrive in focused thinking blocks—what I call containers. They’re short, defined sessions with clear intent but flexible edges for ideas to take shape. Knowing which is which is the real skill.
How to use Parkinson’s Law wisely
1. Match the method.
Use containers for creative work. E.g. Brainstorm five possible newsletter subjects | 15 minutes.
Use time limits for functional work. E.g. Plan Q4 key deliverables | 45 minutes.
AI tip: Try this prompt to help you decide which is which:
Act as a productivity mentor.
Review this to-do list and classify each task as either functional (routine, structured work) or creative/problem-solving (open-ended or analytical).
For each task, suggest whether I should set a fixed time limit or create an open ‘container’ for focused thinking.
Present the results as a simple table with columns: Task | Type | Recommended Approach | Suggested Time Frame.
Also note which tasks could be delegated or batched to reduce context switching.
2. Shrink the window.
A 60-minute task often fits into 45 when you decide it will.
3. Add mini deadlines.
Use short checkpoints to keep progress visible.
4. Timebox your calendar, and stick to it.
Set clear finish lines and honour them.
When your brain knows where the edges are, you feel calmer, clearer, and more energised. And you’ll get tasks done in less time.
The new currency of performance is Energy + Attention + Time.
It’s not about more, it’s about doing what matters with focus and vitality.
