One of the biggest things that has happened since the HF is the price of Steem dropped almost 40% since it's peak around the time you were getting more money. You have a couple of big posts that made you a good amount of money, but you can't expect to replicate those often. They are nice when they hit, but we can't expect them. You average post may have seen a dip, but there could be other factors. Some people's voting habits changed after the HF and now some pull back on their voting after they vote. I think for someone who started in June, you have come a very long way and should be insanely happy. You've been here less than 60 days and made over $500. There are literally thousands of people who started in June who would love to trade places. Don't quit. Just keep finding things that work. You watched a documentary wrote a great headline and article and made over $300, but have not done another one since? Why are you not doing more documentary reviews? I would suggest instead of posting meme posts, I would watch a documentary and write about it. You made over $200 posting about your favorite artist, but have not done one of those again. That is the stuff you should be talking about. The posts where you are adding the most value are making the most money. Do more of that stuff. Talking about bitcoin to your mom, that is a valuable post. Do more of that and I think you will see your numbers start moving upwards. You do have quality posts, but remember, quality is subjective. Focus on adding value.
I hope that helps. I'm rooting for you.
