You need to get used to thinking in that language, and relying on translations the entire time is not useful for this.

with an efficient learning approach and working at it intensively for just two weeks (or longer, if you can’t do it so intensively), you can make a lot of progress in a language. The reason I’m suggesting Esperanto is that it was intentionally designed to be the easiest language you could possibly learn.

So next time a chance to use your target language with a native speaker comes up,

“You don’t know a language, you live it. You don’t learn a language, you get used to it.”
