We've all suffered from "negotiation fever" at one time or another. That's where you get so caught up in the heat of making a deal, you lose sight of the quality of the deal. If you weren't involved and you were just the observer, you'd whisper in your own ear, "Stop! It's not worth it." But it's hard to remind yourself to be objective. Some deals just aren't worth making.
