2️⃣ On not enough focus on repetition...
So we learn by information retrieval (quizzing, elaborating, doing), but we don't just need to retrieve once.
We learn through "repeated" information retrieval attempts. Learning doesn't typically stick unless we retrieve information repeatedly, spaced out over many days.
Repetition can feel VERY boring. You tried the thing. Maybe you even succeeded at the thing. Now you had to do the same thing again a week later? What?!
