Videos are great for this, especially interviews or other formats where the speaking is more natural, rather than rehearsed. Kids shows can help a great deal too, because the host may speak more slowly and use simpler language. Perhaps see if subtitles help you, too. For some people it helps them gain a better idea of what is happening. As you understand more, you can change what age range of shows you're watching.

What i would recommend is finding videos that are up to 10 minutes long maximum and watching them with repetition. If you have a sport in which you enjoy, you can watch interviews of your favorite footballers or favorite actors/actresses who are native or fluent speakers. I feel the learning process will be expedited as long as you are engaged.

Youtube videos by english speakers may help quite a lot, that or watching English television.
