Among all the criticisms, the greatest, most correct and most talented one is time.

Good medicine tastes bitter and is good for illness, but advice when most unpleasant is good for action; Reading and learning is to build your own thoughts and knowledge with the help of others' thoughts and knowledge. Pushkin

does not do to others what he wants you to do.

Flattering you is harmful, teaching you is loving you. Bitter medicine can cure diseases, but sweet words can mislead people. Old beef with chewing head; The old man speaks and listens. (Tibetans) don't listen to the old man, suffering is in front of them. An old family is a treasure. If you don't think twice, you will regret it. If you don't fight the tree, you will plant it if you don't educate it. If you make a lane in the sky, you can't live without it. Listening to your words is better than reading for ten years, but you must be cured of your heart disease.
