I am with Reb. I spent a summer reading My System and some other classic works* when I was ~1500 strength USCF, and my rating jumped to +2000.
I have heard that the prose is challenging, but I enjoyed it. There are plenty of other great books out there, but they all have one major element in common: they are only useful if the reader is willing to put in the work.
I read Nimzo first, then went through the various game collections below. I would not have understood those games as well as I did without Nimzo's help!

* The other books I read that summer include My 60 Memorable Games , a collection of Rubinstein's best games http://www.amazon.com/Rubinsteins-Chess-Masterpieces-Selected-Games/dp/0486206173/ref=sr_1_fkmr0_1?s=books&ie=UTF8&qid=1447718666&sr=1-1-fkmr0&keywords=Rubinstein+chess+greatest+games, Alekhine's My Best Games of Chess, 1908-1937 http://www.amazon.com/My-Best-Games-Chess-1908/dp/0486249417/ref=sr_1_2?s=books&ie=UTF8&qid=1447718628&sr=1-2&keywords=Alekhine+My+best, Life and Games of Mikhail Tal http://www.amazon.com/Life-Games-Mikhail-Tal/dp/1857442024/ref=sr_1_1?s=books&ie=UTF8&qid=1447718756&sr=1-1&keywords=life+and+games+of+mikhail+tal, Zurich, 1953 by Bronstein http://www.amazon.com/Zurich-International-Chess-Tournament-Dover/dp/0486238008/ref=sr_1_1?s=books&ie=UTF8&qid=1447718798&sr=1-1&keywords=zurich+international+chess+tournament+1953, and World Chess Championship, Botvinnik to Kasparov http://www.amazon.com/World-Chess-Championship-Botvinnik-Kasparov/dp/0713453451/ref=sr_1_sc_1?s=books&ie=UTF8&qid=1447718568&sr=1-1-spell&keywords=World+Chess+Championship%2C+Botvirnnik+to+Kasparov
Here we hit upon the main thing that most chess book readers aren't wanting to do. Once I finally started seriously working on the book I've begun with, I am noticing significant progress. Combined with tactics trainer, that is, and mentor. Many players, myself included, want to purchase a chess book and flip through it when you're sleepy, or tired. Looking at it lots of times doesn't do almost anything. Gotta do the work, get out the board and play through all of it, with the variations. We will see if I can stick to it, but I'm positive if I do, it will make a gigantic difference. I haven't read or purchased My System, but I've heard the hype, all the big boys praise it, so maybe I will go for that one at some point, too.
