Barry Moltz: Too many people think that networking is sticking out your hand to shake another person's hand and simultaneously giving her your business card.
Immediately, she says who she is and what she wants. Real relationships are built over a long period of time.
You need to build trust and that takes time and effort. Don't try to trade on relationships too soon.
Always ask what you can do for that person before asking for yourself. As Tim Sanders says. "be a lovecat" by connecting people of like interests together.
