Which brain is more optimistic: Right or left?

Highly recommend the book My Stroke of Insight by Jill Bolte Taylor, brain scientist, who explains clearly that the right mind is all about the richness of this present moment.  It is filled with gratitude for life and everyone and everything in it.  It is content, compassionate, nurturing and eternally optimistic!!  How profound is that?  She is confident that we can find a hemispheric home for each of our characters so that we can honor their identities and have more say in how we want to be in the world.  Please be responsible for the energy you bring into the room, your home, your office, the grocery store and ultimately the world.
