There are many steps:
1. Read books that are translated into english, try to understand them and try to pronounce it carefully.
2. For more, watch tv shows that are translated into english and ask people or someone you can trust to help you and give advice, don't be shy to ask.
3. If your gain a little how about practicing it infront of the mirror like practicing in a public speaking.
4. Use the lessons you learn and express it with your feelings, its okay to make mistakes, CONSTANT practice makes perfect.
5. Last, try to speak it many times as you can or talk to someone who speaks english or who knows to speak it better.
Hope this help >-<
