Learning a Second Language

I've been studying English since I was in high school. I can't really learn English in English schools, [Redundant description] because most of the time they only teach you the grammar rules, sometimes speaking in their mother tongue. [Confusing phrase. Drop it.] So ["So" is okay, but I would choose a more descriptive adverb like "Recently" or a phrase like "Not long ago".] I realized that I don't need to spend my money in English schools. Now, I study English by myself. I use the internet. I listen to the English conversations. and I read books. Sometimes, I speak in English with other people. [Break previous sentence into four individual ones for conciseness and clarity.] That's work for me, Although I always feel like I am saying or writing something wrong, I don't fear making mistakes because I'll learn from them. ["Them" is a little confusing here. Do you mean you will learn from your own mistakes or that you will learn from other English speakers?l]

Great job! Watch out for those extra phrases that don't add much meaning to the sentence and can sometimes make your sentence a bit confusing.
