While I have always found systematic regular study to be the single most important element in language learning is (much more important than methodology or material for that matter). The streak can become a burden. At the end of last year I noticed that I was only logging in to Chinese traditional to fulfill my “streak duty” and didn’t do much besides listlessly turning a couple of pages - waiting for a congratulatory message to clear my nagging conscience. This was a sign I needed to end my 800 day streak. Somewhat unfortunate, as I would’ve liked to get to 1000, but I’d rather cut my losses than letting LingQ become a chore.
