You will never speak exactly like a native. The main reason for that goes beyond technical language skills like grammar and pronunciation. Sounding like a native involves a certain culture that natives were born into. They were brought up in a different environment and went to different schools. It affects the words they choose to use and their overall communication style, which will be almost impossible to fully replicate.

Instead of mimicking how people speak in other countries, I suggest bringing your own culture and accent into communication. Of course, it's important to be understood, so I'm not suggesting that the technical basics of the language are unimportant. But I think we shouldn't blindly copy others' communication styles or be ashamed of our own ways of speaking an international language.

It is important to understand the exact reasons why you are learning the language. You cannot learn every single word, every single idiom, every single piece of grammar.

Language is huge, and it is impossible to grasp it all. But it is possible to focus on the types of conversations, topics, and situations that you will likely get into and learn communication styles that will be useful in these particular contexts.
