Simon Baron-Cohen:

"If you focus only on others, there is a risk that you neglect your own needs. Too much of a focus on your own needs could result in self-centeredness, which itself carries dangers of becoming isolated from social support."

"Being too other-centered means one would never pursue one’s own ambitions, or act competitively, for fear of upsetting or diminishing others. Being too self-centered has the advantage of pursuing one’s own ambitions to the exclusion of all else[.]"
