Reading this book opened my eyes regarding the value of ones network of friends. You need help of other people in whatever you do. If you have the connections with needed people already before starting your new project then you will be off the ground much faster.
One of the most important lessons in networking is to be nice to other people and help then reach their goals. Even cleaning lady in your office is important, call her by name and tell how much you appreciate the clean office in the mornings!
You can take the title of this book literally. Actually you can schedule meetings with interesting people for every lunch. Very few people say no if you invite them to lunch. Usually you can ask your existing network to reinforce the relationship. Its also good idea to identify people you want to meet and find someone in your network to introduce you. When you go to lunch then be prepared. Find out all you can about this person and go to the lunch with a plan. Just keep in mind that these lunches are not only what you want but try to find something how you can help your companion also. From my own experience I recommend not to have lunch with same people every day though. Usually office workers go to eat with their colleagues and this does not help to expand your network too much.
Another important principle is to keep pinging your network. If you do not keep in touch then you will soon be forgotten. Congratulation on birthdays is natural in these Facebook times. From time to time you can give them a call, send an e-mail, invite to lunch or to house party.
Industry conferences are great way to let people know that you exist. Try to get some speaking arrangements. If you cannot get to the big events right away then start with small and eventually the invitations to big events will also come. When going to event try to identify people you want to get to know beforehand. Go early and find these people. After making such initial connection it makes sense to ask them to lunch or breakfast or dinner also later and have more in depth conversation.
