Nhờ sửa bài giúp

Hey, I'm writing this because im bored, and because i want to know how i can improve my English.

Im sixteen years old and I've been studying English since I was ten-eleven so I think that my writing and reading is very good, or at least I hope so.

Two years ago, I started to read books in english.

First i read books I've already read in spanish, and then I read a lot that I haven't.

When I'm reading and I find a word that I don't know I use the Wordreference translator, so here is my question, do you think that look for the meaning in an English dictionary is betten than look for the meaning in your native lenguage?

Another subject, Im good at listening, but not so much, I mean i can understand a conversation or some movie scene without subtitles, but it is really hard to me to understand some song lyrics.

How can I get better at that?

At last but not least, I guess im even worse in the speaking part, mostly because is the one that i got less practice.

Sometimes I confuse the spell o i get stuck because god knows why.

Thanks for letting me know what things i wrote the wrong way. Bye
