First, understand the basics of the platform and how things work. It seems simple enough: create content and get rewarded. But there are many nuances that often frustrate new users and send them away.
I've been developing a Beginner's Guide to Steemit that helps address many of these early concerns and topics on the platform. If you want to check it out, I've got links to all of the Steemit posts in one place if you'd like to check them out: https://ethandsmith.com/steemit.
I would also echo the other answers you've received on this question. Take the time to find a community to join. One of the best places to start is by heading over to @steemitramble and the Steemit Ramble Discord server (https://discord.gg/RHzuFQt). You can get connected with Steemians from all over the platform. There's even a live voice session twice on Thursdays where you can chat with other Steemians and find a good fit!
Also, please let me know if you have any questions. I'm happy to help you find success on Steemit. It takes a lot of hard work, but keep it up!
