The goal in learning to pronounce another language should be communication. Can I be understood?
Based on this research, for native speakers who are listening, fluency is more important than pronunciation. In other words, our ability to put words together accurately, smoothly and fluently, is much more important than trying to pronounce like a native.
Fluency requires a wide vocabulary and a sense of which words normally are used to describe certain situations, and which words are normally used together with other words. To acquire this you need to read and listen a lot.
