Why Do People Change Over Time?

You look back and think:

“I wouldn’t have made this choice before.”

What once felt important no longer does.
What you once ignored now feels essential.

Why does this happen?


Answer: Because Time Changes the Direction and Strength of Our Inner Vectors

Time is not just something that passes.

It actively reshapes us.

It changes:

  • what we want
  • what we value
  • how strongly we feel those things

In other words:

👉 time acts on our internal vectors

This is why we change.


How Do Vectors Change Over Time?

Answer: In two ways—rotation and scaling.

1. Rotation (Change in Direction)

The direction of a vector shifts.

  • When we are young → we seek freedom and challenge
  • As we age → we value stability and responsibility

The same person,
but the direction has rotated.


2. Scaling (Change in Strength)

The intensity of a vector changes.

  • The need for recognition may weaken
  • The desire for health or peace may grow stronger

What once drove us strongly
may lose its force.


👉 These two changes—rotation and scaling—
are what we call “personal change”


Why Do We Sometimes Stay the Same?

Answer: Because vectors have inertia.

Once a direction is established,
it tends to continue.

  • habits persist
  • careers become difficult to change
  • relationships follow existing patterns

This is the inertia of vectors.

However, major events can disrupt this:

  • illness
  • loss
  • new encounters

These can suddenly change direction.


How Can We Understand Growth and Regret?

Answer: As differences between past and present vectors.

Growth

When vectors rotate toward deeper alignment with our values.

👉 We feel more consistent with ourselves


Regret

When we look back with our current vectors
and see past actions pointing in a different direction.

👉 “Why did I choose that?”


Restart

When we accept that our vectors have changed
and begin moving in a new direction.


Time does not trap us.

👉 It gives us opportunities to rewrite our direction.


Why Is It Important to Understand This?

Answer: Because it helps us accept change—both in ourselves and others.

Desires and values are not fixed.

They:

  • rotate
  • expand
  • weaken
  • strengthen

When we understand this:

👉 we stop rejecting our own changes
👉 we better understand others

Change stops feeling like instability.

👉 It becomes structure.


● Conclusion

Time is not just a flow.

It is a force that changes the direction and magnitude
of our internal vectors—desire and values.

Through rotation and scaling,
it shapes our actions and the course of our lives.

Human change is not random.
It is structured—and therefore understandable.
