Confucius
“Is it not a pleasure, having learned something, to practice it at due times?”
“They who know the truth are not equal to those who love it, and they who love it are not equal to those who delight in it.”
“In all things, success depends upon previous preparation, and without such preparation there is sure to be failure.”
“What you do not want done to yourself, do not do to others.”
“To study and not think is a waste. To think and not study is dangerous.”
“To know what you know and what you do not know—that is true knowledge.”
“To see what is right and fail to act on it is want of courage.”
