LinkedIn is a great tool to connect and build your professional network. Use it to forge amazing and long-lasting relationships–even if only get a few pros who are interested to chat–that is certainly worth your while. It is about the quality of the connect and the way you foster it rather than simply trying to connect to as many people as possible.
Do periodic networking and outreach ssessions–extend invites and messages to people that you think can you and you help them. It is all about creating a positive intro to them and evloving from there. LinkedIn can be a phenomenal tool to develop great professional relationships but you need to always exude confidence, be positive and bring value to every conversation.
