We have all lain awake rehearsing a conversation that has not happened yet. This episode is for those moments, when preparing for something difficult has slipped into living through it early.

It begins with a founder I was mentoring, who could not sleep before a difficult conversation, and with my own habit of turning a polite request into a cross-examination in my head. It goes on to Ant Middleton’s idea of the Fear Bubble, Robert Sapolsky’s zebra, and Seneca’s remark, nearly two thousand years old, that we suffer more often in imagination than in reality. And it follows one middle-aged man’s decision to test the idea by jumping off a 300-foot crane.

Along the way it asks what is different between preparing for something and living through it early, why the two feel so alike from the inside, and whether I have managed to stop. (I haven’t.)

The Two Witnesses

A Holmes UnLimited Observation

“One day, this will all be worth it.”

This is something we often tell ourselves when today's demands seem justified by tomorrow's rewards.

But what if you're beginning to question that bargain? Or wondering why an experience you remember fondly didn't always feel quite so enjoyable while you were living it?

The Two Witnesses explores Daniel Kahneman's distinction between the Experiencing Self and the Remembering Self - and what happens when the person who lived an experience and the person who later judges it are not quite examining the same evidence.

Clues from this Observation

• Why do some moments survive in memory while others disappear?
• How can the ending of an experience change the verdict we later give it?
• When experience and memory disagree, which witness gets to speak for the whole case?

A Study in Fear

This investigation has its roots in a family experiment to create a memorable weekend — including a 300-foot bungee jump and the rather inconvenient necessity of having to experience it before it could become a memory.

A Study in Fear

What begins as a family experiment in creating a memorable weekend becomes something rather more revealing.

A 300-foot bungee jump. A crane above a lake. A decision that felt perfectly manageable… until the moment it became real.

A Study in Fear explores what happens when intention becomes commitment, when fear finally arrives, and when the person living an experience encounters the person who will later remember it.

Clues from this case

Why does fear sometimes arrive only when possibility becomes immediate?

What changes when a decision moves from something we are thinking about to something we must actually do?

And when we later decide that an experience was “worth it”, whose judgement are we really hearing - the person who lived it, or the person who remembers it?

Those questions lead into two connected Holmes UnLimited Observations.

Follow the Observations

The Fear Bubble

The Fear Bubble follows that clue into a wider investigation of anticipatory stress - the strange human ability to begin experiencing a difficult future before it has actually arrived.

It explores the difference between preparing for a moment and prematurely living through it, and asks whether fear itself is always the problem, or whether sometimes we simply enter it too soon.

The Two Witnesses

The weekend in A Study in Fear began with a deliberate experiment: could we create an experience designed to become a powerful memory?

The Two Witnesses takes that idea further through Daniel Kahneman’s distinction between the Experiencing Self and the Remembering Self.

The person standing on the crane was, briefly, very uncertain about the whole enterprise. The person remembering it years later is delighted to have done it.

Both are telling the truth.

So which witness gets to decide whether an experience (or perhaps even a period of our life) was worth having?

Once a move becomes visible…
the board itself begins to change.

In this second part of the Holmes UnLimited Observation, Holmes follows the deeper implications of a symbolic act, exploring the strange relationship between policy, perception, and the moments that quietly reshape collective belief.

Because ideas rarely spread through logic alone.

More often, they move through signals, stories, gestures people can actually see.

A conference room in Tbilisi. A remembered moment from Britain in the 1990s. And a growing realisation that leadership may begin not with explanation… but with embodiment.

An observation on narrative, legitimacy, and why the first visible act often matters far more than the perfectly argued plan waiting behind it.

Because strategy may set direction… but action is what makes intention real.

Let the investigation begin.

Before strategy becomes visible…
something small, symbolic, and human usually happens first.

In this Holmes UnLimited Observation, Holmes reflects on a conference in Tbilisi, a room full of cultural leaders and policymakers, and a question quietly forming beneath the surface of the discussion itself:

How does an idea move from theory… into collective belief?

An invitation, a threshold crossed, a gesture that altered the meaning of the room around it.

But sometimes the moments that change perception are not the grand announcements… only the first visible signals that something new is beginning.

An observation on leadership, symbolism, and the subtle difference between discussing change… and embodying it.

Because before people believe in a strategy… they usually need to see a move.

Some absences are harder to notice than presences.

In this Holmes UnLimited Field Note, Holmes reflects on a creative studio alive with movement, conversation, and making… and a founder whose week appeared full in every visible sense.

Her week was full of projects, people and purpose.

And yet, somewhere beneath the motion, something essential had quietly disappeared.

Sometimes, the most important things in our lives are not removed dramatically…
only squeezed out gradually by efficiency, responsibility, and the steady optimisation of every available moment.

A short investigation into space, reflection, and the subtle difference between a full calendar and a sustainable life.

Let the investigation begin.

Every investigation begins with attention.
Not to what we assume… but to what is actually there.

In this Holmes UnLimited Observation, Holmes explores the deeper rhythm beneath the investigative mindset itself: the habits of observation, inquiry, experimentation, and reflection that shape how we move through uncertainty.

Not as productivity techniques or rigid frameworks, but as a disciplined way of seeing.

Across founders, conversations, workshops, and everyday moments, a pattern begins to emerge: clarity rarely arrives through force.

More often, it emerges through careful observation, slower thinking, and the willingness to let reality answer back.

An exploration of curiosity, perception, and the subtle difference between reacting to life… and investigating it.

Because sometimes the most important shift is not finding the answer.

It is learning how to notice the question more clearly.

Some conversations change shape when they are held in company.

In this Holmes UnLimited Observation, Holmes reflects on a bright room in Wolverhampton, a circle of creative entrepreneurs, and a gathering that slowly revealed something unexpected beneath the surface of the discussion itself.

Coffee, questions, and a conversation that drifted somewhere unplanned.

Sometimes the most revealing moments arrive not during the formal session… but when the structure softens and people begin speaking a little more honestly.

An observation on peer learning, shared inquiry, and the strange recognition that occurs when we realise our private questions may not be quite as private as we imagined.

Because occasionally the thing that changes us is not the answer itself…

but discovering we are not investigating alone.
