Metrics That Matter More Than Vanity Numbers
Count what supports behavior: days touched, average time per session, and percentage of mature cards recalled. Let difficult cards inform edits, not shame. If reviews exceed your bandwidth, lower the new-card rate before motivation collapses. Write one weekly note capturing wins, frustrations, and a single experiment for next week. These practical indicators keep your attention on process quality, ensuring retention grows steadily without chasing dramatic but brittle statistics that tempt burnout.
