I interviewed Chartered Accountant, Douglas Shanks, last week about generating results from business networking. When talking about referrals Douglas said "The secret to getting referrals is giving referrals so focus on what you can give".
That simple sentence contains the essence of a successful approach to building your network. Obviously you will want to benefit from the relationships you build with others and you want them to advocate and refer you when they can. This short podcast explains the importance of advocating others in your network first.
