"Writing is not necessarily something to be ashamed of, but do it in private and wash your hands afterwards"

Robert A. Heinlein's quote, "Writing is not necessarily something to be ashamed of, however do it in private and clean your hands afterwards", can be dissected to reveal a multi-layered perspective on the act of composing.

At its surface area, the quote brings an amusing tone, suggesting that composing is an act comparable to others we consider private, such as using the bathroom. This contrast recommends that writing, while not inherently outrageous, is a deeply personal and reflective activity. It may suggest the singular and intimate nature of putting thoughts into words, where a writer looks into inner worlds to articulate concepts, emotions, and stories. This aspect of personal privacy underscores the notion that composing is an exploration of one's inner self, exposing vulnerabilities and credibility that may not be suitable for show and tell without thoughtful consideration.

Further interpretation might point to the notion of composing as a procedure that can get "messy". In this sense, "washing your hands later" could be metaphorical for the procedure of editing and refining one's work. It signifies the importance of tidying up, arranging, and presenting a polished final product, understanding that the initial draft might consist of raw, unfiltered content that requires careful modification.

Additionally, Heinlein may be hinting at the potential consequences or misunderstandings that can occur from composing. When writers reveal or share personal or controversial ideas, they run the risk of judgment or criticism from others. Thus, the suggestions to "clean your hands" works as a preventative measure, suggesting that authors ought to be prepared to distance themselves from their work once it's out worldwide, acknowledging that readers may interpret it in unexpected methods.

Ultimately, Heinlein's quote encourages authors to accept the act of composing with both humor and respect, acknowledging its naturally personal, in some cases chaotic nature while taking responsibility for the narrative they eventually pick to show the world.
