Step 1: Ignore the long descriptions. Reason: the core motivations are what count. Descriptions muddy the waters, because ppl with the same enneagram type can have different socionics types and consequently approach the core motivations in varying ways that are not the same. Ignore traits.
Step 2: Take all 9 core motivations & fears, lay them out on paper. Start crossing out the ones least like you and slowly narrow them down. Look for patterns in why and how you act.
