Don't Close the Year with a Single MBTI Letter
81% of Korean adults know their MBTI. When it's easy to close a year with 'because I'm I / because I'm F,' lay one sheet of coordinates on top of MBTI — and close the year on actual data instead of a single letter.
Mid-November, the weight just before the year closes
Mid-November is where the fourth-quarter close begins, and at the same time, next year's January is no longer far away. 'What remains of this year?' and 'What do I start next year with?' sit alongside each other — which is why starting a review in mid-November (instead of cramming it into the last week of December) tends to land the year more gently.
In Hankook Research's 2024 'Public Opinion within Public Opinion' survey, MBTI familiarity among Korean adults was reported at 81% — meaning a majority of people carry their MBTI letter with them. That makes it easy to close a year with 'because I'm I' or 'because I'm F'. Such a closing offers brief comfort but does little to prevent the same shaking from arriving next year.
Seoyeon's November notebook
FICTIONAL PERSONASeoyeon Park, 24, 1st-year out of college
Second week of November, on a phone call with a friend, she lands on "I think this year was hard because I'm an INFP." After hanging up, sitting at her desk — "…was that really all? How do I write down the shaking that doesn't fit into 'because I'm I' or 'because I'm F'?" — the question stays on the notebook. The friend's words gave some comfort, but a sense remains that the same shaking will return next year at the same place.

Seoyeon's notebook does not close because MBTI is wrong. It does not close because a year's shaking typically grows in a different dimension than a personality axis — in values, motivation, decision-making, and execution. The coordinate that a review needs sits on top of MBTI, not inside it.
A review comes from four axes, not from one letter
For closing a year, Life Portfolio's 76 questions propose four axes of self-management — self-understanding, self-expression, self-design, self-execution. Even the same 'I had a hard year' separates into different roots when looked at across these four axes, and next year's first step changes accordingly.
- Self-understanding — shaking that grows when 'who am I' is unclear.
- Self-expression — shaking that grows when 'where and how to express who I am' is unclear.
- Self-design — shaking that grows when 'in which direction, with what, at what pace' is unclear.
- Self-execution — shaking that grows when the coordinates exist but daily action does not follow.
The same 'because I'm I' year asks different next steps depending on which axis the shaking grew in. A self-understanding axis suggests deeper measurement and interpretation; a self-execution axis suggests redesigning the smallest possible next step.
A year-end review does not come from one letter; it comes from four axes. MBTI is a fine first letter — but to close a year, one letter needs a sheet of four axes laid on top.
How to close a year on a single coordinate sheet
Life Portfolio's 76 questions ask self-management across 11 domains (self-awareness, values, transitions, emotion, relationships, motivation, energy, drive, decision-making, execution, areas of interest) and organize the results into a 4-axis report. Measurement itself takes about 15 minutes; one calm month of interpretation across December is enough.

A year is closed not with a single letter, but with a single sheet.
A MBTI letter is a clue for starting the year; a measurement is a coordinate for closing it. With that one sheet — the same shaking does not arrive at the same place next year carrying the same weight.Frequently asked questions (FAQ)
Q1. What gets left out when a year is closed with a single MBTI letter?
MBTI is a useful instrument for asking 'who are you (personality type)?'. However, questions like 'how did the year go, where did I shake, what should I do differently next year' are hard to answer with a single personality letter. If a review closes with 'because I'm I' or 'because I'm F,' the same shaking arrives next year at the same weight. Year-end reflection asks for a different dimension of coordinate — values, motivation, decision-making, execution — not a personality letter.
Q2. Why start the review in mid-November?
Trying to close the whole year in the last week of December is heavier than measuring coordinates once in mid-to-late November and then slowly interpreting them across December. Mid-November is the first stretch of fourth-quarter closing and is also close enough to next year's January that the two questions — 'what remains of this year' and 'what do I start next year with' — sit alongside each other. The single sheet of paper that can answer both is the self-coordinate produced by a measurement.
Q3. Why take Life Portfolio's measurement when I already have my MBTI?
The two instruments ask different dimensions. MBTI asks about personality type (I/E, N/S, T/F, J/P), while Life Portfolio's 76 questions ask about the four axes of self-management (self-understanding, self-expression, self-design, self-execution). This is not a claim of one being superior to the other — only a difference of which dimension a year-end review needs. Year-end reviews often need values, motivation, decision-making, and execution as coordinates, which a single MBTI letter is not designed to answer.
