Of all the criticisms, the greatest, most correct and most talented is time.
Good medicine tastes bitter and is good for illness, but advice is hard to listen to is good for action;
Reading and learning is to build your own thoughts and knowledge with the help of others' thoughts and knowledge. Pushkin
Do as you would be done by.
Flattering you is harmful and teaching you to love you. Bitter medicine can cure diseases, but sweet words can mislead people. Old beef with a chewy head; The old man talked and listened. (Tibetans) Don't listen to the old man, suffering is just around the corner. An ancient family is a treasure. If you don't think twice, you will regret it. Don't fight trees, sterile trees. If you make a path in the sky, you can't live without it. Listening to you is better than studying for ten years, but your heart disease must be cured.
