You might be experiencing writer's block, possibly due to a decrease in your Medium earnings. This is just a theory.

What should you do? Take a break, which you may have already done. Then, begin writing and publishing again until you find your inspiration.

I believe that consistent effort leads to quality. You might not like your initial work, but it will improve over time.

Lastly, ignore negative opinions as they often reflect the insecurities of others. You're a talented writer, so remember that.
