Hello, @cryptoboiii, and Welcome to Steemit.

Art and photography are among the more popular topics on Steemit, so you might find success in those fields. And of course, the topic of crypto is huge here, so if you can bring anything to this platform on that topic, so much the better.

As an English teacher / writer, I must say that your English is quite good. Have confidence in your ability to write in English, spend a bit of time writing, re-writing, and editing, and you'll certainly create some excellent posts. ☺

Below are a few basic points of advice re posting on Steemit.

1 – Longer posts are more lucrative than short posts. If you make a post of 20–30 paragraphs, it's more likely to earn rewards.
2 – Include some photos, images or graphs, to complement the text.
3 – Make sure the text and photos are formatted properly, so that your post looks attractive and appealing.
4 – Be yourself.
5 – Be interesting and informative.
6 – Create quality content. Steemit is intended to be a platform of quality content. (You will see many insignificant posts with meager content and no quality. Most of those of posts [called “shitposts” by Steemit whale Stellabelle] will earn few rewards and soon pass into oblivion.)
7 – Get online and start curating. Read various posts, comment on those posts you find interesting, and upvote those posts. That’s the best way to attract followers.

Hope this helps for now. Good luck, and Full Steem Ahead!
