It's the kind of friction needed to help note takers who tend to drown in capture bloat—always onboarding, never offloading.

Speed and efficiency are, in my opinion, arbitrary gauges of success. The shear number of productivity czars prophesying about a "future without friction" are innumerable to be almost comical. In contrast to these efficiency futurists, when it comes to zettelkasten, I am pro-friction. But, not just any friction. Eufriction. Eufriction is good friction. Just as weight training, writing a book, and giving birth can all be considered a form of eustress[6], so too is folgezettel a form of eufriction.
