First notebook entry: Introducing myself

I'm learning English because I want to expand my circle of friends. I want to break through my language limits and speak fluently. English will help me understand 90% of the people in the world. It is great way to communicate with other people and learn about their cultures.
My native language is Russian. It's a very difficult language with a long history. I dream about teaching it someone in future.
I live in Moscow, I've been living here since I was born. I have an opportunity to live abroad, because I work in chemistry and have colleagues in Canada, Denmark and England, one day I will be able to work there. But I think I won't leave Russia forever.
Something about my interests: I like travelling. My hobby is hitchhiking, even though I have enough money to travel by train for example, but it's not as intresting. I like walking through in the countryside with my friends (Moscow is so boring to me). I also like to listen to music, sometimes I visit my friends' concerts.

First notebook entry: Introducing myself

I'm learning English because I want to expand my circle of friends. I want to break through my language limits and speak fluently. English will help me understand 90% of the people in the world. It is great way to communicate with other people and learn about their cultures.

My native language is Russian. It's a very difficult language with a long history. I dream about teaching it sometime in the future.  [Perhaps you meant, "to someone in the future.]   I live in Moscow. I've been living here since I was born. [Shorter alternative:  "I have lived in Moscow since was I was born.  Or: ..... since birth.] I have an opportunity to live in Western Europe, because I work in chemistry and have colleagues in Canada, Denmark, and England.  [I added the word "Western" because you already live in Europe.]  One day I will be able to work there. But I think I won't leave Russia forever.

Something about my interests: I like travelling. My hobby is hitchhiking, even though I have enough money to travel by train for example.  But train travel is not as ["so" is ok; "as" is a bit better.] interesting. I like walking through ["in" is ok; "through" is better] the countryside with my friends (Moscow is so boring to me). I also like to listen to music, and sometimes I visit my friends' concerts.
