A dream

My first rist dream is to speak English fluently . I know I will do it some day but that may takes a lot of  much More time I think . 

That's why. Languages are like plants. You need to take care of them every day so you can become able to speak fluently in the language you want to learn. If you don't practice them every day, you may risk to forget the words that you've already known. 

If you want, I can help you with your English skills. Just take a look at my calendar and let me know when are you going to be free to talk to me. 

A dream

My frist first (only)  dream is to speak English fluently . I know I will do it some day, but that may takes much <em>a lot of </em>More time I think .

This was really good! A small tip would be that you can use 'only' instead of first.

Hope this helps!
