Agreed @sirstacksalot! Lots of imagination and creativity. Maybe fearlessness, now that I think about it. :) Those two qualities exhibit a lack of fear.

I met an interesting fellow in Spain once and after a LOT of gin and tonics, he asked me "What are you afraid of???" And I said, "Except spiders, bungee jumping and a couple other reasonable things, not that much." And then he said, "Then Do. Something. Bizzare."

And my mind splattered itself inside my head.
