Watching English TV shows or movies can also help with pronunciation. Just be careful which ones you watch, some pronunciation can change depending on whether its American English, British English, etc. 

I agree and that's coming from a native speaker. The rules for pronunciation are so inconsistent! But with perseverance and diligence, I'm sure you can prevail. You have to learn it as you go unfortunately.

Try your best to mimick the sounds of native speakers. Don't worry, you'll get the hang of it sooner or later :)
