I recommend just following people who interest you and writing comments. Don't feel like you have to write great articles to be a valuable part of what's going on here. Steemit needs people who read, upvote and comment.
I've learned so much since joining Steemit about six months ago. I think it's been life changing for me. Most of that has been due to what I've learned from reading other people's writing and then putting what i've learned into practice.
Hope that helps,
