Never bring a cannon on stage in Act I unless you intend to fire it by the last act.

How unbearable at times are people who are happy, people for whom everything works out.

I swear fearfully at the conventions of the stage.

When you describe the miserable and unfortunate, and want to make the reader feel pity, try to be somewhat colder - that seems to give a kind of background to another's grief, against which it stands out more clearly. Whereas in your story the characters cry and you sigh. Yes, be more cold. ... The more objective you are, the stronger will be the impression you make.

When men ask me how I know so much about men, they get a simple answer: everything I know about men, I learned from me.

A good person will feel guilty even before a dog.

All of life and human relations have become so incomprehensibly complex that, when you think about it, it becomes terrifying and your heart stands still.
