Stop stopping. Stopping is the worst thing. Stopping breaks your momentum. Stopping is the start of decay and regression. When you choose to stop, you set yourself the task not only of getting back up to the same speed as before but also to the same altitude — the same level of Japanese. Taking a break from Japanese will hurt your Japanese. A lot. Each time you stop, you lengthen the road to fluency. When you stop, you quite literally become like Sisyphus: forever pushing the rock of your Japanese ability up the hill, only to have it roll down each time you pause. And just like Sisyphus, you have to retread the same ground to get back up where you were. Always restoring, never progressing; it’s a huge freaking waste of time.
