I think of it differently. There are maximizers, satisficers, and doormats. Maximizers are the ones who will go all-out to get the best deal, and sometimes even play the system. They're the ones who know that you can get a box of cereal for $3.79 instead of $5.29 at another store. They'll also come up with excuses to line their job interviews on the same week so the offers roll in at the same time and they can start a "bidding war".

Most people look at maximizers, in the context of negotiation, as being a bit sociopathic. I disagree; I think it's sometimes quite reasonable to take a maximizing strategy. It can be exhausting, but I wouldn't call it sociopathic.

Satisficers have a goal and a sense of "good enough" and, as long as they're north of it, they're happy. Doormats are the ones who take what's given to them. Being a doormat is the worst. You never win by being a doormat.

The problem with "ask for nothing at all", in the workplace, is that it makes you a doormat, not a satisficer.

On the other hand, you have to know when to maximize and when to satisfice (is that a word? It is now.) There's a time for each. Usually, you want to satisfice on salary and maximize on project quality and work culture. But there are exceptions to that rule.
