I’ve been using SuperMemo for 15 years, in fact I just finished up my flashcards for today :) It definitely is useful but it isn’t the grand answer to all of life’s problems. It makes it very easy to remember stuff you want to remember but takes some training when it comes to how to structure desirable knowledge as a simple flashcard. Over the years I’ve rubber handed in how much I use SuperMemo, but the happy medium for me seems to be 1. I usually finish my flashcards first thing in the morning, 2. Get in the habit of “thinking with flashcards” by summarizing ideas into single sentences and 3. I keep an ongoing text document in my Notes app on my phone of information I find that is worth remembering. If SuperMemo had a robust mobile app that synced with the Windows program, it would be ideal. Using my Notes app seems to be the easiest alternative that I’ve found.
