I feel like the implication is that, if you're ever content with your job, you're doing it wrong -- if you're NOT trying to constantly get promoted, then just quit, because you have no place in the workforce. I don't even want to seek more money -- I'm making more than enough as it is.
Also I'm pretty sure my lack of networking is going to fuck me over eventually, too.
Eh, yes and no. Being content and comfortable where you are is awesome. When I was in my early 20s I had a paid off house I'd bought cheap as a repo and rebuilt the inside of and a decent car paid off. My bills were extremely tiny and was damned comfortable and blew money left and right and had plenty of time for gaming and whatnots so I was content with it. Then economic crap happened and I lest my good job and had always ignored the networking thing too. after a year of searching i ended up getting a much worse job at around $10/hour. not a fun job, but my bills were tiny so it paid them and left time for fun. Still good.
Then I met the girl who would become the wife. Her nursey job and mine paid about the same, she eventually moved in and we started planning wedding things. Neighborhood had been getting worse, tons of houses being abandoned, drug busts, several shootings very close by. Girl had something go bad at work and it messed her back up and she was off work. With wedding savings and bills on me the crap job I'd been content with wasn't cutting it at all... couldn't find anything else, though. Had no contacts and no replies to resumes sent. Neighborhood was becoming a place we didn't want to be very quickly, house was paid off but because of how bad the neighborhood had gotten had virtually no resale value, didn't have the income for anything better... was not fun times.
Content is awesome and I'm back to a company and position I'm content in and living in a place we're content with. I've just learned to try to keep things lined up to move forward to something higher paid where I am if needed and take the time to keep in general touch with a few former bosses/colleagues I respect. It isn't something that comes naturally to me, but I can no longer be content when I know one or two sudden big issues could pull the rug out.
