A little self-presentation

Wassup guys!
First of all, let me introduce myself.
My name is Rodrigo, as you can see in my profile. I'm from Brazil and I am 22 years old. I don't know why I like English, maybe it's because I've been been playing video games since I was just a boy, and I always had to read what was written in those games.
Now, I have a reason to learn English more than ever. My girlfriend started to learn English on her own, and I realized that I need to be with her on this journey. How? Talking and chatting to her. Yeah, that's the best way to learn a new language in my opinion. Of course, reading a grammar book is good too, but I think you have to talk and chat withanyone who knows a little bit of the language in order to simulate "real life", you know?
Well guys, that's it. I'm at work (yeah, I shouldn't be writing it right now), and as I'm writing this text very fast, without doubt I've made a lot of grammar mistakes, so, in order to help me improve my English, please guys, correct me!

See ya!

Hello Rodrigo,

Just a few small mistakes, you have quite a good level of written English.

Hope this helps

Bob
