I always pass on good advice. It is the only thing to do with it. It is never of any use to oneself.

If you pretend to be good, the world takes you very seriously. If you pretend to be bad, it doesn't. Such is the astounding stupidity of optimism.

If one plays good music, people don't listen and if one plays bad music people don't talk.

Arguments are extremely vulgar, for everyone in good society holds exactly the same opinion.

The only thing to do with good advice is to pass it on. It is never of any use to oneself.
