From the article:
In business networking emotional intelligence is an important element also. The sensitive handling of questions and conversational leads is a great way to establish trust and help find areas of common ground, whilst not being seen as pushy or interfering. A good way to develop emotional intelligence is to practise the pregnant pause. This is not as stupid as it seems. A deliberate pause stops you from jumping in too soon and it also helps with listening skills because it forces you to think about what has been said and actually answer it in a measured way. All in all emotional intelligence is a powerful asset to nurture.
PS -- The BEST way to develop your EQ is with coaching and THE EQ COURSE! And ... because of what Brian mentions (above), introverts can make some of the best "networkers."
