Drawing Lines, Making Cuts — On Deciding and Moving Forward

Lately, I’ve found myself returning to Sakanaction’s Shin Takarajima (New Treasure Island).

The song was written for Bakuman., a film about a young aspiring manga artist. But what it holds is not limited to manga.

People who make things — writers, musicians, actors, founders, designers — are always moving toward some next frontier.

Some days bring a flash of insight. Other days, nothing moves at all.

Excitement and impatience mix together, and still, we keep walking, looking for the next island.

Whenever I listen to that song, one act comes back to me.

Drawing a line. And making a cut — deciding, then letting go.

That act appears in work, in family life, in creative practice, and in the way we now live with AI.

1. To draw a line is to decide — and cut

Manga is made of lines.

The moment a line appears on a blank page, meaning begins to rise.

A line divides the world. It creates contour. It creates boundary. It says: this side, and that side.

At the same time, a line is irreversible.

Sometimes it becomes regret: “Why did I draw it there?”

Sometimes it becomes clarity: “Yes — that was the right line.”

Either way, a line is never neutral.

To draw a line is to choose:

• what to keep and what to discard
• what to hold yourself and what to hand to someone else
• what to move forward today and what to stop for now

In work and in life, this happens constantly.

A line sharpens judgment. A line clarifies responsibility. A line makes the next step possible.

To draw a line is to decide. And to decide is, in some sense, to cut.

Once a line is drawn, you do not stay at the point of possibility forever.

You walk.

2. New treasure islands are not only for adults

The search for a “new treasure island” does not belong only to adults.

Children live inside it too.

A child who loves running through a park throws themselves into the wind. Their heart rises with the thrill of motion.

And sometimes they fall. Sometimes they scrape a knee.

But both the joy of running and the pain of falling belong to the same act.

You only receive them by moving.

To run is to choose.

To try is to choose.

To step forward is to accept that delight and pain may arrive together.

That, too, is a kind of line-drawing.

Not a formal one. Not a strategic one.

But still a real one.

Try. Decide. Move.

Children do this every day, often more honestly than adults.

3. We are always drawing lines in ordinary life

In work and in daily life, we draw lines all the time.

• how far to go today
• what to postpone until tomorrow
• what to prioritize
• what to leave unfinished
• what to protect
• what to release

If we refuse to draw lines and try to hold everything at once, judgment becomes cloudy.

Records disappear. Responsibility blurs. Fatigue accumulates.

And later, it usually exhausts everyone involved.

That is why boundaries matter.

We need lines in order to delegate. We need lines in order to protect attention. We need lines in order to keep moving without dissolving into endless ambiguity.

Not every line is dramatic.

Many are quiet.

But quiet lines often shape the whole structure of a day, a team, or a life.

4. In the age of AI, line-drawing becomes an operating prerequisite

AI does not remove the need for boundaries.

It intensifies it.

We are now asked questions that arrive before any answer:

• what can be delegated to AI
• what must remain human judgment
• where reasons should be recorded
• who reviews what
• how exceptions are handled
• how updates happen over time

AI does not draw the line for us.

That remains a human task.

What AI can do is expand the material around the line: options, comparisons, drafts, possible structures, candidate paths.

But deciding what to trust, what to keep, what to approve, and what to refuse — that still belongs to us.

This is why line-drawing is no longer optional background work.

It becomes part of operating design.

If you run quickly while staying vague, you break quickly.

If you automate before defining the boundary, you scale confusion.

So in AI-enabled work, boundaries are not merely governance language.

They are part of the system’s basic survivability.

5. If I must draw lines anyway, I want to choose an adventure I can carry

If drawing lines is unavoidable, then I want to choose lines I can carry.

Perhaps even lines I can carry with some sense of aliveness.

An age of change keeps asking the same questions in new forms:

How will you decide? Where will you cut? What will you take responsibility for? What will you refuse to pretend you can still hold?

I draw lines today too.

As someone building work. As someone living with a wife and child. As someone trying to move responsibly inside uncertainty.

That does not mean every line is correct.

It means I want to draw them consciously.

Because the point is not to become perfectly certain.

The point is to move in a way that keeps responsibility, direction, and vitality together.

If we must cut, let it be in service of something living.

If we must choose, let it be toward an adventure we can still stand behind.

Closing

A line is not only restriction.

It is also form.

It makes movement possible.

It makes responsibility visible.

It allows the next step to exist.

In creative work, in ordinary life, and in the age of AI, we are asked again and again to decide where one thing ends and another begins.

So perhaps the question is not whether we will draw lines.

We will.

The question is what kind of lines we will draw, and whether we are willing to carry them forward.

May your route through work and life be a good one.

Bon voyage.
