A calligraphy brush worth 68 yuan, compared with one worth 12 yuan

has a clearly improved writing experience.

A calligraphy brush worth 128 yuan, compared with one worth 68 yuan
has improvements that have become relatively subtle.

This shows that
the usefulness of a product
after reaching a certain critical point,
tends to become saturated.

After that,
the added value is almost entirely emotional value—and emotional value
has no limit.

For insights into trading,
what we need to be wary of is
how to avoid, during the trading process,
over-consuming “emotional value”
and to make the money as practical as possible.

As for business/entrepreneurship,
it involves searching for projects that can provide
an excess emotional value,
because pricing power has no boundaries at all.
