" Being wisely selfish and being selfless can amount to very much the same thing. There are centuries of anecdotal testimony on this point—and, as we will see, the scientific study of the mind has begun to bear it out. There is now little question that how one uses one’s attention, moment to moment, largely determines what kind of person one becomes. Our minds—and lives—are largely shaped by how we use them. "
