How Did You Come Up With the Ten Sparcotypes?

How did you come up with the ten sparcotypes? I honestly wish it wasn't ten. It feels so slick to me. But literally, starting with giant list of jobs, titles, and then making list of whatar. The sweet spot between those five states is, what is how i define that feeling of coming alive or being sporkd How did you develop the questions in the first place, and how did you determine how specific answers would lead you to a specific sparcotype yet? "I was always taught um to do everything you can to understand the conversation that's happening in somebody's head"
