How not to forget what matters

Henrik Karlsson writes about deliberate knowledge-keeping practices—what the ancient Greeks called *hypomnemata* (personal notes used as external memory). The essay draws on thinkers like Seneca and Foucault, who saw note-taking not as record-keeping but as a moral and intellectual discipline: writing to shape one's character and remember what one values. Karlsson contrasts this thoughtful approach with modern note-taking tools (e.g., Roam, Obsidian) that optimise for capture and retrieval, often at the cost of reflection and clarity about what truly matters. The piece is part of a growing online conversation about "tools for thought," digital minimalism, and reclaiming attention from productivity culture.
