Allot of us are doing Japanese mainly in our free time and I believe its a good idea to share how we manage that time to use for Japanese as effective as possible.

Here are mine :

Use you're commuting time for JapaneseDo youre Kanji/vocabulary repititions to make sure you can get that out of the way as early as possible in the day . So that you can go over to the fun parts of Japanese .

Something that often helps me (which I do way to less) is make to do lists before I go to bed and I write them in concrete steps . I even write the simpelest thing on them like ''review kanji'' even if its asumed I will being doing those anyways the day after. Just being able to cross it out once I actually did it feels so good.

what tips can you share ?

I used to go days without sleep to finish projects and I still do this to a certain degree.
I tend to reserve Sunday for rest and study. If you really need something done I think sacrifice and not time management is the way forward.
