In case you haven't seen my introduceyourself post.
I joined Steemit in June 2016 and then made a HUGE mistake...I didn't post anything until August...Oh Brother that lack of effort cost me some serious STEEM Power. I actually remember reading @danthemans introduceyourself post ,it's probably worth reading a lot more than mine...but like a fool I did nothing....
Anyway the point of this pitty-party is that its never too late to start posting... I thought I had nothing interesting to say, I lacked confidence in my writing ability and like most people struggle with time demands of work , family and social commitments, but through persistence and dedication I have finally crack the 60 reputation.
So get stuck in...if you feel you cant write a post,read as many as you can ,make notes , upvote and follow interesting users.. the day will come when you feel you have a post bursting to be released.. look to get involved with one of the curation guilds that help new Steemians like 
This is an amazing and life changing ecosystem we are all part of, embrace it and I guarantee you will receive gifts far more valuable than the monetary value rewards.
