The first time to watch CNN

This is my first time to watch CNN. And I couldn't understand what they were talking about. They speak so quickly, and what I got after a news was over was the pictures they shown on the screen.
Maybe I haven't learned enough for all these years. I should spend more time and do more effort on English learning.
However, I won't give up watching CNN every day, because I want myself to be used to it. And perhaps one day I will suddenly understand what they are trying to say. It won't be just a dream if I do so.
