There was a period in my childhood (roughly age 8 - 12) where I was starting to run headlong into some pretty bad spikes in my Assigned Spiky Profile at Birth, and so I started to believe that exceptionally good spikes actually meant something, in more than just a "yeah, I do these things pretty well" sort of way.
Started to believe.
The TL;DR was a strong but short-lived interest in IQ tests and similar things, which I was (fortunately) nudged out of by family members at first and then by greater exposure to other people's strengths, weaknesses, and overall life experiences.
