I guess it depends. I'm not really good at relationships, but I can be a very normal guy in almost every scenario. So, I'm not like asking my manager what did he do during the weekend (but if he talks about it, I listen and follow the discussion), nevertheless he's a professional and if I do my job the way they like it, I'll get a promotion (if I don't, then I need to switch to another company). Similarly, I'm not friend of my work colleagues, but I'm definitely not a dick. It's easy to not be a dick; it's not easy to be "friendly". I don't have a work network at all. The people I have worked with in the past are Linkedin connections now (I do have the phone number of a couple of people, though), but I have never relied on them to get a job (among other things, because they live in different cities, countries and continents).

So, many of us are doing just good by being really really minimal social beasts. I think the key is to not being a dick, but that doesn't require being a social person in my experience.

To me this feels like you are thriving on regularly getting promoted? My guess... maybe that is for you the required confirmation that you are doing well?

Indeed I think the importance of a work network is overrated. My LinkedIn is hopelessly outdated and to switch jobs, all I seem to have/need is my CV and professional years. In my experience interviewing is very much like dating.
