It makes sense that humans developed this social behavior in order to facilitate mate selection. At a primal level, what is more important to us than furthering our species?
As a communication consultant, I talk to many people who dislike networking or find that it feels fake. And I definitely sympathize with these feelings. But personally, love networking because, when it works best, it is a way for people to connect and help each other. Help each other learn. Help each other meet new people. Help each other grow.
The idea that networking may have started as a way to build our species is inspiring to me. (That's the kind of dork that I am!) Maybe it will help you love networking, too!
