What has worked for me is Maintaining organized .
I am able to follow up (and have a great memory)
It is important to maintain organized in order to close the deal.
It is not just about the event and collecting business cards.
It is about what do you do afterwards.
You have to, have to, have to stay organized and follow up!!
I take it an extra step and find them
on LinkedIn. This way if I want to send them a message, I can.
Moral of the story, stay organized !!!!
