I would like to write my own lyrics in english

I want to know more improve my English because I believe that it's is important to travel and to have a good job.
We don't know what will happen in the future. Maybe I will be in U.S.A., maybe in London or in another place.
But I know that I really love singing and writing lyrics in my language.
I also would like to write my own lyrics in English, because the songs in this language sound perfect!
There are a lot of combinations of vowels to do rhymes, and when I sing or I listen to songs in English, it sounds great in my ears.
I think now it's impossible for me to do a song in English, because I don't have much vocabulary in English, and there are a lot of expressions that I don't know. But I know that in the future, I will do make songs in English.
I hope that and I will do this to make my dream come true.
