Learning vocabulary is about adding up small bits - you can't rush results.
Tips
history
Roots in 《战国策·秦策四》 ('thin layered into thick, few gathered into many') and 《汉书·董仲舒传》 ('few collected become many, small accumulated becomes vast'). The four-character form crystallized from these classical lines.
usage
Practical and motivational - common in advice about saving money, learning, exercise, fundraising. Often paired with verbs like 坚持 (to persist).
