Learning English is so fantastic!!!

I WOULD LIKE MY NOTEBOOK TO BE CORRECTED BY A NATIVE ENGLISH SPEAKER, PLEASE.If IT IS possible, put my mistakes into capital letters, thank you :)
Hello there, I´m here to tell a LITTLE bit about my English story.I´m Adriano and I´m a native Portuguese speaker. When I started to learn English, I was 15 years old, in my High School.I studied for 6 years and, after this, I completely stopped.I learned just simple vocabulary and some basic grammar rules.I loved English but I didn´t HAVE AN interest in continuING my English studies.
After this, in the year of 2000 (ten years later), I started to study Computer Science at university.So, I restarted to study English.The computer programs are always in English and I felt uNcoMfortable when I didn´t understand the language.I WAS SO fed up about IT.So, I started classes in English here in Brazil.I made some replacements English tests that include writing, speaking and grammar skills, and my English level was Elementary.I made 2 years of English classes and I stopped again ( in 2002).
But currently, I´ve been learning English since 2010 on internet, youtube videos, watching films and reading some news in magazines and newspapers on internet.Now, I´m totally focused in pronOunciation practice in order to reduce my strong brazilian accent.Of course I still made grammar mistakes when I´m speaking, but I´m absolutLY right that make mistakes is part of the learning process.Learning a foreign language is not a easy task, it requires a lot of patience, I know.But it is not an impossible dream. I´m certain I need to study a lot to improve my pronounciation and to achieve fluency, it´s a hard time to do this.I intend to get fluency in 2 years :)
English is a beautiful and very interesting language.I study English for various reasons: first, because of my future job.The second one for travels and the third one is to be bilingue.That´s my goals...
Last years I didn´t have any English teacher or tutor, I´ve studied by myself and I´m enjoying it.But I recognize that a tutor would keep me in direct contact with the language and I would make progress faster.Sometimes I get frustated when I don´t understand slang words or an idiom in English, specially when I´m watching a film or reading The newS.Informal English, slangs and idioms are very often used by native English speakers, and they are very tricky and complicated to understand in context.But I try to understand them and I never give up. Lets keep on learning English.Bye-bye English learners :)
