Where the streame runneth smoothest, the water is deepest.
Children and fools speak true.
The finest edge is made with the blunt whetstone.
The greatest harm that you can do unto the envious, is to do well.
If you will be cherished when you are old, be courteous while you be young.
Whatsoever is in the heart of the sober man, is in the mouth of the drunkard.
