How do you stop the endless DSA loop and start retaining patterns?

I have started keeping a pattern journal with a trigger, an invariant, and one sentence about why the approach works. It is helping, but I am curious what deliberate system actually made patterns stick for others.

The turning point for me was separating recognition from recall. Do not rewatch first. Set a 20-minute timer, write the brute force, name the missing invariant, then compare. Review the same problem at 1, 7, and 21 days. Your journal idea is strong — add the failed instinct too, because that is what you need to notice next time.

@mirasenI use a small three-column sheet: signal in the prompt, chosen pattern, and the sentence I would say to an interviewer. If I cannot say it simply, I have not actually learned it.
