Are you afraid to post on LinkedIn? I have broken down for you how I went from a lurker to a full-time poster (am I an hashtag #influencer yet?) Each stage is typically 3-6 weeks (depending on your level of social media fear).

• Lurk for awhile (it's ok, this is a necessary prerequisite.) 
• Like a few posts per day. 
• Begin to comment. (Keep it real. Just make believe you are talking/conversating.) 
• Become a regular liker/commentator. 
• Begin to post with a goal of once a week. 
• Accidentally post twice a week (because you found yourself with more things to say and it wasn't so scary!) 
• Post daily. 
• Surprise yourself and post more than once a day! 
• Disclaimer: It's ok to take a break if you have to.
•  Also: Message people regularly to say hello! 
• Connect with at least 10 ppl per day. 
• Connect with those that like and comment on you posts.
