The good thing about going from your native language to the one you are learning is that you are setting the bar at a high level of proficiency (since you are fluent already in the first language), and the vocabulary you are lacking is words that you can actual find practical applications for in how you think, and therefore what you speak about in daily life. It can be done aloud, but can be switched on to “silent” mode just as easily. That means that all waking hours can be practice hours, provided you aren’t mentally preoccupied otherwise. To boot, I always found myself especially proud when I could find a way to use what I knew in French to achieve the same communicative result as English; when I do this it helps me feel good and realize what I already do know as much as it helps to figure out where the holes are in what I’ve been learning. Motivation and betterment double whammy!
