Finally stopped grinding random LeetCode problems and started doing the same 20 problems on a two week cycle, recall got so much better

Was doing the classic thing of solving a new problem every day, feeling good in the moment, then blanking on something nearly identical two weeks later. Switched to picking 20 problems across core patterns and just cycling through them every two weeks instead of chasing novelty. Third pass through, I noticed I wasn't re-deriving the approach anymore, I actually remembered it. Slower to feel like progress at first, but it's the only method that's actually stuck.
