Forum exercise
Lifelines
Plot the moments that shaped you. Then look at the shape.
You draw your life as a chart — the turning points, the losses, the choices, the surprises — and you present it to your forum. Everyone presents. It takes one long meeting or a retreat, and it changes what every meeting after it can be about.
Most forums do this once, early. Some redo it every five years and compare. The act of building it is doing at least half the work: you decide what mattered, what to include, and what to leave out. That's already your real story.
Before the meeting
Make your chart
Then, or now?
Your vertical axis is a rating, roughly −10 to +10. Before you plot anything, decide what it measures: how the moment felt at the time, or how you see it now.
Most people blur the two and end up charting their conclusions. The stronger version plots both — one line for then, one for now — and pays attention to where they pull apart.
If two lines is too much, pick one and say which it is. Ambiguity here is what makes a lifeline feel flat.
Turning points, not milestones
Plot the moments where something actually turned — a choice, a loss, a door that opened or closed, a time you were most yourself or least. Graduations and promotions only belong there if they genuinely moved something.
Roughly twelve to twenty points tends to work: enough to show a shape, few enough that each one earns its label. Past thirty, the chart reads as noise and nobody can see the line.
Extend it at both ends
- Backward: start before you were born. What was going on with your parents? What did you inherit that you didn't choose?
- Forward: take the line past today. Where do you want to be? What would make you proud looking back from eighty?
The forward extension is the part people skip and the part that produces the most useful conversation. It forces a real question you can't answer with history: what do I actually want?
Track dimensions separately
Work, money, health, family, friendship, spiritual life — run them as separate curves and something usually appears that a single line hides. When one goes up, what happens to the others? Which one have you been paying for the others with?
Include something you've rarely told anyone
Not because disclosure is the point. Because the group calibrates to whoever goes deepest. If everyone brings the version they'd give at a reunion, you'll spend a long meeting confirming what you already knew about each other.
You have confidentiality. This is the exercise it was built for.
The traps
- The childhood sink. Eight minutes is about ninety seconds a decade. Spend six on your first eighteen years and you'll narrate the years your forum can actually help with in a rush.
- The résumé. If a stranger could reconstruct your chart from your LinkedIn, you haven't made one yet.
- The flat line. "It's all been pretty good" is a choice about what to show, and the room will read it as one.
- Overbuilding. Four hours in a design tool is usually avoidance. A legible hand-drawn chart beats a beautiful evasive one.
Wide open
Hand-drawn on graph paper, a spreadsheet chart, a photo collage, a map, a stack of slides, a set of objects on the table. Pick the one that fits how you actually think — the gallery below is a starting menu, not a list of requirements.
Send your chart to the group 48 hours before the meeting.

Six ways
Choose a format
All fictional composites. Click a chart to enlarge it.
Ordinary
The classic
One line, birth to now, drawn by hand in twenty minutes. Start here unless you have a reason not to.
The spreadsheet
Same thing in Excel. Nobody has ever been marked down for this.
Four lines at once
Work, family, health and money tracked separately. Watch what health does while work climbs.
A different angle
Thriving, struggling, dormant
No rating, no curve — just which parts of your life were alive in which years. Best format for spotting what you let go dormant.
Photographs
Eight images, connected by a line that still rises and falls. For people who'd rather show than plot.
The forecast
Eight panels of weather across one life, including the years ahead. The fastest of these to read and the easiest to extend into the future.
At the meeting
Thirty minutes each
Everyone presents in the same meeting. It's long. That's the point — the group crosses something together it can't cross one presentation at a time.
As an audience member
Ground rules
- Curiosity over advice. Ask, don't fix. Nobody presented a problem.
- Reflections beat questions. "I see a person who kept choosing the harder room" often lands harder than any question you could ask.
- Patterns, not prescriptions. What do you see — not what would you change.
- The presenter owns the follow-up. They choose what to explore, and when. You don't assign it.
- Everything stays here. Including the chart.
Why it's worth a whole meeting
What it does
For the presenter
Building it is the work. You decide what mattered and what to leave out, which means you tell your real story rather than the one you usually tell. Then the forward half asks the question you've been avoiding: what do I actually want?
For the audience
Context for everything that follows. When someone brings a challenge six months from now, you hear it against a whole life. And seeing someone's vulnerabilities makes you more willing to show yours.
For the group
You stop being people who meet monthly and become people who know each other. Later, someone can say "this sounds like that pattern from your lifeline" — and be right.
For moderators
Running it
The exercise mostly runs itself. Four things are yours.
You go first
Always. The group calibrates its depth to the first chart it sees, and it will not go deeper than you did. If you present a careful version, you'll get eight careful versions back and the meeting will be pleasant and useless.
Set the container in sixty seconds
Say four things before the first chart: confidentiality is absolute; we share experience, not advice; you choose your own depth and nobody is owed more; this is not therapy and we're not equipped to be. Then start.
Hold the timer, and hold the silence
Cut people at eight minutes — kindly, but cut them. The pacing problem is always the same: too long at the start of a life. And when someone cries, do nothing. Don't reach for tissues, don't rescue, don't fill it. Wait.
Decide the afterlife of the charts
Before the meeting, agree what happens to them: kept in the group's hands, deleted after, or held by each member alone. Then schedule the callback — put one lifeline theme on an agenda within sixty days, or the whole thing evaporates into a nice memory.
Two situations to plan for
The résumé. Someone presents a career summary with no interior. Don't call it out. Ask one question: "Where were you hardest to live with in that stretch?" It usually opens.
Acute distress. If a member is in genuine crisis — not moved, not tearful, but in trouble — the forum is the wrong container and pretending otherwise doesn't serve them. Stay with them, and help them get to professional support.
Where it comes from
The lifeline reached HBS Alumni Forums through YPO, where a version of it has been in the forum canon for decades and is sometimes called the grandfather of retreat exercises. It has close cousins elsewhere: the "river of life" used in facilitation and participatory work, the life-story interview in narrative psychology, the crucible work in Bill George's True North, and structured life review in gerontology. They arrived independently at the same instinct — that a life becomes legible when you draw it.
