Iām part of the ācanāt study during commuteā club (on bike or WFH), although my current position is fully remote.
For OP:
First, think of the little time slots where you usually fit your reviews/lessons. I feel that, for me, the study slot that goes uninterrupted the most is the lunch break one. In the morning itās easy to rush, in the evening itās easy to give priority to other tasks or family, but during lunch time Iām usually free to do my own thing even if itās just for 15 minutes.
I think Denzoās tips are great, and the only thing Iād add is: find that specific, uninterrupted slot that works the best for you and focus on having a disciplined routine tied to it. Even if thatās just a daily trip to the toilet and you only have 10 minutes and your phone, stick to it. That way youāll hardly find a reason to miss your daily minimum (even when youāre away on holidays) and can easily hold yourself accountable if you happen to miss it.
Personally, I feel that setting a very small minimum goal and seeing the rest as a bonus works wonders for my motivation compared to trying to fit a bigger, āmore productiveā goal into a routine that is bound to get shaken every now and then by mundane events. Having a small minimum goal rarely makes me less productive than if I had a larger one (since I feed on that āman, Iām on a roll, letās do this!ā feeling and enjoy the feeling of successfully overachieving), and also doesnāt make me depressed when I happen to miss my bigger goals for completely legitimate and unexpected reasons (which can also easily snowball into a chain of missed goals, since you already āfailedā once).
Your miles may vary, naturally, but this is the system I found that works the best for me. Hopefully this information might help you find your own routine.
Iām not the original poster, but in my case (since I feel the same), I think itās just a matter of human psychology: we remember negative events more than positive ones, and āfailingā is something that sticks with you more easily. Part of me feels disappointed for failing and wants to make sure that specific kanji doesnāt fool me more than once, so my memory holds onto that kanji more. Also, it helps to re-study it while isolated, instead of in a batch of lessons where your memory can get muddy and lump several readings/meanings together.
