English Language Challenges
The English laboratories here at university I think that was useful at least for me. It helped me to improve my orthography and get used to write a lot in English.
Making all these blogs was sometimes fun, sometimes bored actually, because the topic wasn't always something interesting for me.

I definitely have to expand my English vocabulary, and improve the fluency because sometimes I get lost in my ideas and stop talking, I don't want this to happen in a future, talking with foreign people.
So if I want to really leave these problems behind, I will have to probably watch TV series in English, read English texts frequently, hear people talking in English in different accents to develop my hearing, etc.
