Always preserve some unsettled point of conflict in any deal for the very end, so that you can blow up a deal once the momentum has taken root and the intellectual investment has been made, and everyone is committed. This allows you to crush minor points of petty theft that tend to occur by the participants in the negotiation and at the eleventh hour use their desire to profit from invested time and energy to veto a large set of sketchy provisions.
