So I quit my job to focus on my startup...
btilly: I once asked a very good negotiator for the best book he could recommend on negotiation, and he directed me to Start With No.  (URL: http://rcm.amazon.com/e/cm?lt1=_blank&bc1=000000&IS2...)I've read it, it made sense to me, I've noticed a number of good negotiators doing things it suggests and my (admittedly few) negotiations I've done since have gone much better.
