WRITING ABOUT LEARNING

I have studied English for many years, I started studying it when I was 4 in my nursery school, and I continued learning it at school until I was 18 and I finished high school. Furthermore, I have been attending English classes in the afternoons for 5 years until I obtained my C1 last year. 4 years ago I was invited to go to my English teacher’s house in the state of New York (EEUU).
I started learning English because I had to, but then while I got older I realized that it is very important nowadays for many things such as finding a job, travelling throw the world… I also enjoy watching films and series in original version and reading books in English, so for that reason I needed a high level.
In my personal case the most difficult thing is to write in English, I need to practice but I always feel lazy to do it, even though I read some books to improve, I really need to read and write more.
Now, so as to continue my learning experience, I am attending conversation classes and I am planning to improve my grammar by working with a grammar book.
