I think if you made a double axis to represent personalities,
There is one axis that is person who is willing to get on a rollercoaster (do adventure, be iconoclastic)
There is an orthogonal axis that is person who screams (reactive/touchy/emotional)
So you have four quadrants:
Person who screams in life and never gets on a rollercoaster
Person who doesnt scream (tough) but also never gets on rollercoaster
Person who doesn't scream (tough) and gets on rollercoaster (tolerant of adventure) = (usual persona of tough)
Person who screams all the time but still gets on the rollercoaster = me LOL
