We make assumptions. A huge one made by many is that others “already know” how we feel about them, their special occasions, what's important to them, things we can do to help them, or that we're interested in what they have to say. This includes family, friends, colleagues, customers and prospects.
So… being that we assume they already know all that, we don't communicate with them. Besides, it's a lot of effort to find their contact info and to keep up with what's going on in their lives.
Or is it?
If you put all your contacts into an easily organized and retrievable system, then no, it's not a lot of effort. And the payback is massive!
It goes without saying you should keep in contact with family and friends, but it's equally important to stay in touch with your business contacts.
You can't have a business without developing relationships. It's that simple.
