I have read many of your blogs. I use networking as a tool for professional advancement as you repeatedly suggest, but, frankly, it is not working. When I meet people and give them my card, they seem eager to help. When I contact them, few respond and those that do withhold critical information. My longstanding professional colleagues are not helpful either. They do not return my calls or respond to my emails. I am very disappointed in your strategy. Networking is not working.
