Personally, I am scattered and/or self-sufficient. The main implication is that I constantly question both my actions and their ultimate implications. This may have more to do with the complications of freedom (light job and family responsibilities) that affects my emotional center.
These thoughts easily segue into our basic nature as humans. A recent New Yorker article on Neanderthals [more here] speculated that the main difference between them and us -- a related species that overwhelmed and absorbed them -- is our sociability. People are just better at relating, cooperating and dominating other species -- for good or ill.
Bottom Line: Humans have basic needs. Once those are met, we have more complicated emotional needs -- some of which can only be satisfied by inner peace.
