Follow-Up is the key to success in any field.
Give yourself between twelve and twenty-four hours after you meet someone to follow up. If you meet somebody on a plane, send them an e-mail later that day. If you meet somebody over cocktails, again, send them an e-mail the next morning.
But remember – and this is critical – don’t remind them of what they can do for you, but focus on what you might be able to do for them. It’s about giving them a reason to want to follow up.
