When you start learningbetter to say (to learn) a new language and you are a kid (as a kid),you don't (do not)understand anything about it but now, when I look back, I see that that themes were easy peasy. (I find those themes very easy.)
I remember my English teacher. with a lot of affection (S/he was very impressive) and since that day I fell in love with the subject better to say (I have interested in English) and I would like to improve my skills in the future!
That day marked my life as student and as a person and I'm very grateful to it because I have never had problems in this subject and I can have a fluid conversation with any kind of problems! I think it is better to reword this part.
