Is networking hard to learn?

Is networking really as difficult to grasp as some people make it out to be? I've heard that it involves intricate strategies and constant effort to maintain relationships, but is it really that challenging? Or is it something that can be learned and honed with time and practice? I'm curious to know if it's a skill that's inherently complex, or if it's more about perseverance and dedication to building connections. Can anyone who's mastered the art of networking share their insights on this question?
