The old saying is that the secret to success isn’t what you know, it’s who you know. Keith Ferrazzi certainly believes this to be true, and with his book Never Eat Alone (co-authored with Tahl Raz), he outlines how valuable an extensive network is to succeed in business and life. Beyond this, he gives a step-by-step guide as to how to start, grow and maintain relationships that can boost your prospects. In his book, Ferrazzi demonstrates how immensely useful building connections can be. His key point is that everyone you know also knows people and therefore presents more opportunities to expand your network and career.
