I find that in the BJJ world many people get bored of drilling and want to learn something new. Then they do that new technique 50 times and want to learn something else. But in Judo we do uchikomi and we do 10,000 repetitions of the 1 judo throw and we just keep on doing it forever.
Yes we have slightly different setups but to get very very good at a particular technique you must just keep doing it and doing it and doing it, until it becomes natural and almost second nature.
I found this clip of female World Submission Grappling Champion and she is getting interviwed but the footage is of her drilling basic techniques and positions but that's why she is world champ. Not because she knows alot of stuff but because she drills over and over and over again the same technique until its perfect.
There is a Bruce Lee quote that is something like "i don't fear a man who knows 10 000 kicks, i fear the man who has done 1 kick 10 000 times." - what a great saying and there is a lot of truth in it.
So just keep on Drilling
