Key insight: Your second brain system should match your work pattern, not your aspirations. Zettelkasten is powerful but requires consistent linking — it rewards researchers and writers who think in connections. PARA is simpler but demands regular archiving — it rewards action-oriented professionals who work in projects. Most people need a hybrid: PARA for organisation, Zettelkasten-style linking for insight.
