I negotiate professionally. I'm still tempted into one or two books a year on the subject. But the only one I'm ever tempted to recommend is Jim Freund's Smart Negotiating. Very modest in its claims.
Negotiation is a lot like public speaking. The first, most important thing is getting past the idea that it's something you're supposed to be afraid of, actually doing a deal, and realizing you got away with it. Not "crushing" the other side. Not scoring a "win". Just working through the process and ending up better off for it.
Once you're confident enough to practice, it probably won't be hard to find opporunities. Most other people still avoid it, after all. From there you can learn.
