My original goal when I started WK a year and a half ago was to take the JLPT 5 in December 2017 and reach WaniKani level 50 by 7/1/18, but crap hits the fan sometimes and I put everything in vacation mode last June. Wasn’t planning on taking such a long break but just started up again, resetting from level 12 down to level 4.
This isn’t my first break, I’ve taken several over the years for various reasons. It’s frustrating because it feels like stuff is slipping away but when I start again it all comes right back, and some vocabulary/grammar actually cements itself in my brain better after a break.
My new goal is to take the JLPT this coming December. For WK, my goal isn’t to reach a specific level, but to maintain a steady pace for the next year and see where I end up.
Whatever goals you make, don’t stress too much if the time comes and goes. Just pick up and start again and keep on keeping on.
