Ialways cheer up immensely if an attack is particularly wounding because I think,well, if they attack one personally, it means they have not a singlepolitical argument left.
Duringa negotiation, it would be wise not to take anything personally. If you leavepersonalities out of it, you will be able to see opportunities moreobjectively.
Neverforget the power of silence, that massively disconcerting pause which goes onand on and may at last induce an opponent to babble and backtrack nervously.
