Think long term: The best time to network is when things are going well. Remember the best results come from long-term investments. Do not wait until you find yourself out of a job to start networking.
Network online: Join LinkedIn, Facebook, Twitter and actively participate. Remember it is easy to get lost behind your computer screen the most powerful form of networking occurs face-to-face.
Join groups: Join groups that meet in real rooms. Remember you are there to develop relationships over time. It may take a while but these groups will lead to you the right people.
When you join that organization and network, don't expect great results right away.
