There seems to be lots of reasons to network, and more importantly, keep networking. The process should never really stop. The need continues even though you may know every member in your networking group and could have even become good friends, outside of business, with many in your network.
Ongoing repeat reminders as to whom and what you are looking for are important parts of networking. Situations change, business contact needs change with them. Letting the other people in your group know what you currently need is critical in receiving effective leads. Supplying the group with the information is an on-going part of networking.
At the same time when your needs change, so do the needs of other members as well. You need to keep apprised of what they may need so you can produce the leads desired by fellow members. The more effective leads you can give, the more the group will supply back to you.
