You will improve your language skills this way, but if your skill level isn't high enough it's going to be exhausting to the native speaker as well.

I have been living in Denmark for 15 years now, and it's still easier to do conversations in English. When I speak Danish it requires more mental capacity from the other side.

I am speaking Danish from time to time, but it's only to get better at it. The English proficiency in Denmark (and probably the Netherlands) is so high that you need to be really good at the native tongue before it is easier than English in conversations.

This is my point. especially in a country where everybody speaks English anyway. you will never be better at Dutch than English so by that logic. it will always (or at least for many years) be more difficult to talk to you in Dutch. so, ask the hard question:

Are you learning it to actually talk to other people?

If yes, just do it. to many people it is endearing if you are struggling with a language. And if they don't like it they probably just don't like talking to you in general so learned or not doesn't matter.

I think many people are scared of talking and use language learning as an excuse for fear. You can start talking to real people or you can keep learning and never talk to real people and then what's the point.
