In addition to the parent comment, there are many books to supplement the development of one's communication skills. Some that I've read and found useful include The Definitive Book of Body Language and How To Win Friends And Influence People.
The greatest show on Earth - Richard Dawkins was an excellent read.
Surely you're joking Mr Feynman by Richard p.Feynman was terrific read by a very small bit can considerred offensive or at the least dated in its outlook but if you can get past that its great!
I recently finished a book on ID called "Masters of doom" by David Kushner which I rather enjoyed as well.
I also love reading about crackers from the (mostly) 80's and I can recommend.
