First notebook entry: Introducing myself

I learn Eanglish, `cause I wanna go to Australia in the future. But for the time being I don`t do anything my dreams will come true, but I try to do something to change my life. So, I learn English, `cause I want to be a relevant worker too. I want to add, I really like English and it`s the most important thing why I learn English.

*In proper Engilsh you say because, not 'cause. Also, you cannot use "but" at the begining of a sentence. You can use "however". Most people don't mind, unless it's a professor or teacher.
