I've beaten myself up many times in college for seemingly forgetting everything after classes finish. I spent a bunch of time trying to figure out how to learn and retain better. I tried Anki a bit but would inevitably forget things as soon as I stopped too. Forgetting is frustrating, and a situation where I -know- that I knew something before but not anymore is doubly so. But.. ultimately I think I've arrived at this view as well.

Your brain is not wired to remember things that you don't use. If you want to continue remembering, you have to continue engaging with the topic, and a lot of the advice in this thread is IMO just that (just, with a specific regimen / kind of engagement). It's completely natural to forget.

In fact, I'd go further and suggest embracing the forgetting and relearning cycle. If you really need to revisit the topic, you can relearn it again, and it'll be faster than the first time. And maybe you'll forget another time -- that's OK too, you can pick it up again even faster. In the end it's the discipline of relearning (the particular topic, and in general!) that actually continuously hardens. IMO there are parallels between this mindset and SRS -- though without the shame when you forget or miss a day of practice.
