Recently I finished The Analects: A collection of of Confucious' teachings and found, without a doubt, that it should be placed on a list of must reading for everyone. It not only tells you about some history of the man but also his knowledge and insight and advice is there for free.
There are hundreds of his " sayings " to remember and should be available and placed in a safe place as you may want to refer to them as you navigate your way through life . . . several are etched in my mind and this one is at the top: ( You better write this one down ).
" To be wronged is nothing unless you continue to remember it. "
If this is not priceless, I don't know the meaning of priceless.
