These people usually have immediate contact with what they are trying to learn and they learn it full-time during the day. They also allow for many mistakes, more mistakes than the average learner is allowed to do. Would you ever say that ‘‘as long as you can place the stones with at least one liberty you are ok, no need to learn all those pesky rules about eyes, ko, ladders and corners’’? I don’t think so. Same goes for languages. (Silly syntax follows) ‘‘You speak ever you put the rock with the one liberty and you nice?’’ (This kind of sentence is supposed to be acceptable as far as those internet gurus are concerned)
If you needed to learn for some specific reason (job, exams, Go tournaments) you’d have learnt your material already. You can try giving yourself a goal, e.g. an exam or a competition.
My advice, however, would be to keep doing what you are doing, because you’re obviously doing it for fun and deadlines don’t matter.
Edit:
On second thoughts, don’t take my advice. The exam system for HSK has changed since July 2021, it was all over the internet for a very long time and I only realised it just a few minutes ago. My advice leads to no progress.
