"Good Enough" vs. Perfectionism in Learning

Perfectionism in learning is sneaky. It disguises itself as thoroughness: I need to understand this completely before moving on. But complete understanding of chapter one while ignoring chapters two through ten is not thoroughness — it's avoidance wearing a diligent mask. You'll learn more by moving forward with 80% understanding than by polishing one topic to 100%.

This doesn't mean being sloppy. It means knowing when to move on. If you can explain the concept to someone and use it in practice, that's good enough for now. Depth comes with revisiting, not with staying stuck. The student who reads the whole textbook imperfectly learns more than the one who perfects chapter one and never opens chapter two.
