Hello Paulina!
I can see that you are a new Steemit member and I want to welcome you aboard in the first place.
Although, in fact, I was motivated to leave you a comment for an entirely different reason. Please, take it just as a friendly suggestion or advice!

I noticed your article was copied/pasted (the English version) from the website where you are publishing your blog posts (your blog-site) to which home-page you provided a link at the end of your article (here). Therefore, I would like to draw your attention and bring to your awareness the following.

Steemit is mainly the platform and community created to support original content creators. I don't have a single doubt about the originality of your work posted here. So, it's not even the slightest problem! But it might become the problem for the following reason.

Here, on Steemit we have some bots that scroll the pages for plagiarized, copied/pasted and other sorts of abusive or malicious usage (most often somebody else's) content. Unfortunately, those bots are not always very smart and their algorithms are not that highly sophisticated to recognize (as it would be in your concrete case) that in question is the same individual who is publishing on both sites.
As well, there are some members too who are doing more or less the same job manually. But humans also make mistakes, so something like this may easily slip from their sight or maybe they just wouldn't dig that deep to figure it all out.
In both cases, it could easily turn out the ugly way not only being downvoted by those bots or a single member who might be convinced how he/she discovered another plagiarism, but as well with a horde of accounts that follow them.
In that case, your already collected earnings (through upvotes) may be decreased or even dropped down to total ZERO with such wave of downvotes. And from my point of view the worst, it might result ending up on the so-called "Black List" among other members who tried to abuse the platform system (in different ways).
Placing the appeal and explaining why you should be removed from such list might be quite long and frustrating process.

You are a too good content provider to run into such stupid trap.
Therefore, and as I am the one who would whenever is possible rather chose "better safe than sorry" way, I would like to suggest you the following solution (no matter how ridiculous it might sound to you).

When you are bringing here some article that you have previously published on your blog-site or elsewhere, and especially when you are adding to it some additional value (as you did with this one here by Polish translation), just post e.g. at the end of your article some kind of "Source or Bibliography attribution comment" with the exact link to the article you are republishing here (not the main, home-page link).

It could be something simple e.g. like this...
"Source: Own article previously published on my blog-site."
or something similar. You would probably figure out something even better! 😉😊

P.S.
Sorry for such a long comment and detailed explanations but I truly hope you would have some use of it and avoid unwanted and unnecessary troubles.
