For me it was languages. I think it is really the most important thing. I once heard of a phrase: how many languages you know, so much time are you human. And I totally agree with this phrase. If you know a lot of languages, you can communicate with different people all over the world. You can make new friends and of course have a lot of practise. Personally, I am from Ukraine 🇺🇦 and almost everyone in our country knows other languages like Russian, Polish, Serbian, English. And as for English, I think it is the international language and in many countries, you will be understood if you speak English. I have three favorite languages: Spanish, German and English. Which do you like and want to study ?😉🙃
