If you're great at taking business cards when they're handed to you but not so great at remembering who gave them to you, where and what you were talking about, reader meep offers a simple but smart trick:
A friend told me about this excellent networking tip: when you get a business card, write where and when you met the person, along with important facts you may need later on the back. This way you can say, "Oh, remember when we were [there]and you asked about [this] " as a conversation starter later on.
Got another method that helps you remember more about the person who handed you the card? Let's hear it in the comments.
