There are different levels of fluency. At the very least, being “fluent” means being able to communicate well enough to take care of daily tasks, including shopping, ordering food, communicating with drivers, getting medical care, etc.
That’s a lot different, for example, than being fluent in the business lingo of your target language. To keep focused, and motivated, define your fluency goals based on your own needs. Then, when you reach a fluency goal, congratulate yourself on a job well done. After that, if you so desire, make a new fluency goal. Doing this will give you motivational “victories” in what can otherwise seem like a never-ending conquest.
