Hello, Ilya, and Welcome to Steemit.

That a great, brief introduction. And as an English teacher / writer, I must say that your written English is very good.

There are many Steemers for whom English is a second language, and many of them do their best to write Steemit posts in English.

Several of them do bilingual posts. This young lady – @sweetsssj– makes bilingual travel posts that are very popular and lucrative. Here's another guy with bilingual posts – https://steemit.com/steemit/@mystis/a-bilingual-post-on-how-to-make-steemit-global-une-publication-bilingue-pour-faire-connaitre-steemit

So, if you can, it might be a great idea to make bilingual posts. That way, you can instantly double your readership!!

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!
