主题：国人讲英语（一） CNN　对邓亚萍的访谈 -- pxpxpx

I once read a nice article about networking. It categorizes relationships into 5 types: steal, beg, deal, like, love. Only the latter three are sustainable relationships. In other words, effective networking. In a certain setting, only a subset of relationships are available to be achieved. This perfectly matches your point of "useless networking".
