First time writing in on italki

Today, I'll start to using this system website, italki.
The first time I came to know about italki was when I was watching English videos on Youtube.
I am studying English in Seattle, but I am frustrated because I can't understand completely what native speakers are saying and I am troubled, with especially with my speaking skills.
I want to say goodbye to my former myself who can't speak English well and I want to talk with my American friend, Bruce more fluently.
