1/3 Investigator-Martyr
You need to dig into something thoroughly before you feel ready to commit, but the real learning usually happens once you're actually doing it and hitting friction along the way. Do your homework before starting something new, and once you're in it, treat mistakes as information to fix on the spot rather than something to avoid.
In detail
The Personality Sun falls on Line 1, which needs thorough research to build a sense of security before acting, while the Design Sun falls on Line 3, which learns through repeated trial, friction, and adjustment. Together the two lines form a cycle of researching first and then validating through trial and error, unlike Line 4 or Line 5, which don't require that same foundation before moving.
