There are few experiences more painful than being rejected. We vividly remember the hurt of not being picked for a sports team, not being invited to a social event, or not being accepted to university. Our basic human need to belong causes these incidents to stick with us through the years. Even as adults, at various times in our careers we're not selected for jobs, promotions, or projects; or even less significant benefits such as parking spaces, preferred offices, or new computer equipment.
