Linkedin helps you to become a leader and find success. Leadership is all about people from beginning to an end. This the best definition of leadership. Either you are linked in or you are left out. It is hard to believe but it is true. If you are not a proficient LinkedIn user your personal and career progress is in doubt. Networking is key. Team = Together Everybody Achieves More. Networking people means empowering them as opposed to networking with them on a daily basis and not producing any fruitful outcome. The equivalent of 320 pages (80 x 4) in a standard book are presented in a Corporate Manual type publication i.e. 80 letter size pages for a business owner or the Corporate World Manager so that you can use it in your office on a daily basis. When I became proficient in LinkedIn it had some 60 million users towards the beginning of April 2010. I then predicted 100 million users rather soon as there is a new user approximately every second. There is no limit to the power of duplication.
