Dilbert is a gross exaggeration but does show that office people are bizarre. I see only two yellow lights but that's because I don't know enough about you.
The first is I have no idea if you can handle office people. You can't discipline them like your kids unless they're young and you want to become a matriarch. The charm techniques you use on your husband can be applied in the office, if you want to operate like that, but it's more dangerous. Otherwise, you could be frustrated by some people who are lazy, uncooperative, obsessed, overworked or incompetent. And you can't do everything yourself. If you are on a committee of some club, then you're already used to it.
The second is motivation at the job. The job or the work culture must interest you, otherwise you will be going through the motions again. A lot of housewives take low ranking jobs to get out of the house and meet other people and I suspect you're the same. If you're a career ambitious, high brow intellectual like bionerd or me, then you'd be making a mistake and you ought to study first.
Once you're in, for the first month, you'll be too busy discovering how everything works to be worried about low self-esteem. Then your voiciferous self will plug into the gossip networks. Then you'll get your first paycheque. You'll be fine.
