Simplicity Beats Complexity

The world has a natural rhythm. When we remove noise, clutter, and unnecessary complication, clarity appears. We see what matters. We see what lasts. Simplicity isn’t the absence of effort – it’s alignment. It can become a pillar, a guiding operating system for how we work, decide, and lead.

Like a seagull soaring with the wind, life – and work – gets easier when we move with the currents instead of against them.

As an accountant, I’ve spent my career inside complex systems. Tax legislation. Financial

statements. Business structures. Regulatory frameworks. Complexity is unavoidable in our

profession – but confusion is not. Over time, I’ve learned that the best outcomes rarely come from adding more layers. They come from stripping things back to what actually matters.

I’m David Fagan, Managing Partner of mbf Chartered Professional Accountants, and

I’ve spent decades helping Canadian business owners navigate decisions that

materially affect their livelihoods, families, and futures. What experience is simple:

Simplicity beats complexity – in accounting, in business, in investing, and in life.

Why Simplicity Works in Professional Judgment

We all rely on internal frameworks to make decisions. Some people call these mental models – ways of thinking that help us interpret problems and choose a path forward. The better the model, the clearer the decision.

When it comes to simplicity, two models guide my thinking: Occam’s Razor & Irreducibility

Occam’s Razor reminds us to start with the simplest explanation or solution. Most problems don’t need heroic thinking – they need clean thinking. Fewer assumptions. Fewer moving parts. Fewer stories layered on top of the facts.

Irreducibility is the counterbalance. It reminds us that every system has essential

components – elements that cannot be removed without breaking the whole. We simplify boldly, but we don’t cut past the point where the structure collapses.

Together, these ideas create a powerful discipline:

• Don’t add what isn’t needed

• Don’t remove what must remain

This is how trusted professionals operate. They may not name these models, but they use them instinctively. When you do, you land in the sweet spot – simple enough to work, complete enough to rely on. That’s where good decisions are made, and where good systems endure.

Simplicity Across the Professions

When you zoom out and look across other fields, the same pattern shows up again and again.

Simplicity wins in accounting.

It wins in engineering.

It wins in medicine.

Accounting – When Saying Yes Breaks the System

I’ve seen this play out firsthand. Two accounting firms started around the same time. One proudly said, “We can do anything,” and said yes to every request. Over time, growth brought a familiar complaint: “We can’t get anything done.” Complexity had quietly taken over.

The other firm took a different approach. They said no often. They focused on a few simple things and repeated them well. One firm stayed busy and stressed. The other built something that lasted.

Engineering – The $30 Fan

Lean Six Sigma training tells a famous story about a factory struggling with a “major conveyor malfunction.” After $150,000 in diagnostics, the true cause finally appeared. Bob, an assembly-line worker, had plugged in a $30 fan that was blowing products off the belt.

Unplug the fan. Problem solved.

Sometimes the issue isn’t sophisticated. It’s obvious – once we stop overengineering the answer.

Medicine – Think Horses, Not Zebras

In medicine, doctors are taught a simple rule: when you hear hoofbeats, think horses, not zebras. Start with the most likely cause. Only chase complexity when the simple explanation fails.

Simple first. Complex second. Even in life-and-death decisions, simplicity leads.

Why Experience Pushes Us Toward Simplicity

Early in our careers, complexity looks impressive. More work. More clients. More projects. More plates spinning in the air. Complexity feels like progress.

But as responsibilities grow, something shifts. Experience teaches us that simplicity is strength.

We begin subtracting instead of adding.

We turn down noise instead of inviting more in. We learn that saying no

isn’t restrictive – it’s protective.

Simplicity builds consistency. Consistency compounds. And compounding – whether in

processes, trust, or wealth – is where meaningful results come from.

Complexity, on the other hand, hides mistakes and drains energy. Simple systems are easier to follow, easier to fix, and easier to repeat.

A Cautionary Tale from Investing

Even in investing, where complexity is often celebrated, the lesson holds.

Long-Term Capital Management was built by some of the smartest minds in finance – Nobel Prize winners, physicists, mathematicians. Their models were elegant and precise. On paper, they looked flawless.

But the system relied on layers of leverage and assumptions so tight that even small deviations could cause failure. When markets behaved differently than expected, the strategy unraveled quickly. Billions were lost. Investors were wiped out.

Genius didn’t save them. Complexity became fragility.

Why We Choose Simplicity at mbf

At mbf Chartered Professional Accountants, simplicity isn’t about doing less work. It’s about doing the right work, clearly and consistently.

Complexity raises costs, creates stress, and increases the chance of mistakes. Simplicity creates clarity. You understand the structure. You understand the risk. You understand the trade-offs.

Whether we’re helping a client make a tax decision, structure a business, or plan for the future, our role is the same: reduce noise, remove unnecessary complexity, and focus on what truly matters.

As Warren Buffett once said, “There seems to be some perverse human characteristic that likes to make easy things difficult.” The wiser path is to step over one-foot bars, not seven-foot ones.

The Strength of the Simple Path

When decisions align with how systems naturally succeed – fewer moving parts, fewer

assumptions, fewer points of failure – progress feels steadier and more durable.

As accountants, our responsibility isn’t to impress with complexity. It’s to guide with clarity.

Because in business, in accounting, and in life, there are no extra points awarded for difficulty.

Simplicity wins.
