“To write an autobiography of Groucho Marx would be as asinine as to read an autobiography of Groucho Marx.”

The New Spirit

The Autobiography of a Sexually Emancipated Communist Woman (1926)
Context: Nothing is more difficult than writing an autobiography. What should be emphasized? Just what is of general interest? It is advisable, above all, to write honestly and dispense with any of the conventional introductory protestations of modesty. For if one is called upon to tell about one's life so as to make the events that made it what it became useful to the general public, it can mean only that one must have already wrought something positive in life, accomplished a task that people recognize. Accordingly it is a matter of forgetting that one is writing about oneself, of making an effort to abjure one's ego so as to give an account, as objectively as possible, of one's life in the making and of one's accomplishments.

Deception: A Novel (1990)

These two books full of life, shocked me greatly. Your roaring of forty years like spring thunder, knocked at the door of my living grave throughout the whole book. At this time, silence lost its effect, the fire of my life was lit, I want to come to life and go through great anguish, immeasurable joy, dark despair and enthusiastic hope, throughout the peak and the abyss of life. I will calmly go on living with an attitude you taught me until I spend my whole life.
