Steemit is a very fickle social media environment, you could be doing really well one week then then nothing the next, that is that nature of this place.

You never can tell what will be a hit and what will bomb miserably, my advice post about what you want to write about, and comment on other posts too. Most important upvote other people at least as much as your own posts/comments, and yes even tiny upvotes are a sign that you are interested in the content people post. Don't be discouraged about tiny upvotes, just enjoy what you do here and not worry about the rewards too much, if you only think about the rewards you won't like being on Steemit.

Think of Steemit as social media that has the possibility of real rewards, Facebook doesn't offer that, or Twitter, or Intagram, or... Good luck in you Steemit journey.
