A year's plan lies in spring, and a day's plan lies in the morning. 4, black hair does not know how to work hard early, white hair regrets reading late. Rome was not built in a day. 6. Nothing is difficult in the world, if you put your mind to it. 7. It is difficult for a teenager to learn, but an inch of time is not light. 8. Indulgence and diligence are wasted in drama, and actions are destroyed in thinking. 9. Swallows know the ambition of swans. 10, aim high. 1 1, people gather firewood with high flames. 12, a threesome must have my teacher. Hope to adopt.
