I'm perplexed by the personality typology theory, MBTI. I've studied it, for over 5 years now, and still can't identify my type. It is likely either the INFP or the INFJ. Dichotomously, I always test as INFJ, but the Cognitive Functions more often call me an INFP, on tests. Then, I read articles calling: INFPs, "messy but adaptable," and INFJs, "organized planners." I'm definitely the latter... but this still doesn't feel right. Neither type seems accurate enough.
It took me only a month apiece, to learn my Socionics type (EII-INFj) and Enneagram type (4w5).
Socionics' Model A is presented far more abstrusely than MBTI's cute infographics, but I far prefer the former's content. In Socionics, I was able to deduce my type, by realizing, "Okay, I definitely belong to both the Delta Quadra and the IJ Temperament. Therefore, EII." I've also never failed to test as an EII, and agree with the result completely, even after studying Model A, and its 16 sociotypes, for about 7 months, hitherto. I hold that tranquil certainty, of knowing my type, in Socionics. Some say that you can translate between MBTI and Socionics types, but that's a novice's mistake. No type, within either theory, perfectly matches another.
In the Enneagram, my diagnostic tests tend to result in Types: 1, 2, 4, 5, and 9, but primarily 4. Type 4w5 feels right, and I find solace, in that certainty.
I feel like abandoning MBTI, despite having: binged its articles and enjoyed its presenters. I intend to master these personality theories, so knowing my type matters. I might be a special subtype of the INFP or INFJ, so perhaps, I'll check those out sometime.
For now, I identify as an EII 4w5.
