Cell 3
The third cell is an interest in exact things: technology, science, order in one's belongings and thoughts.
What the count means
Empty — an interest in exact subjects is not innate, but it isn't closed off either: such people often come to technical fields through practice. One 3 — the usual level. Two or more — a pronounced pull toward system and structure, bordering on pedantry.
What to watch for
A strong third cell with a weak sixth produces someone who loves figuring things out but doesn't like carrying them through to a finished result.
