Writers of all people tend to be familiar with the power of ritual in one’s life. After all—that’s one of the reasons behind engaging in writer’s prompts. The familiarity of ritual can help to put one in a particular mindset, go after a certain goal, work on a difficult project or personality trait, etc.
Today, write about a lifelong (or career-long, or the equivalent) ritual that a person uses and how that affects his or her life. If you prefer to write non-fiction, journal about the place of a ritual in your own or a relative or friend’s life. If you prefer to write fiction, create, examine, or explore the place of a ritual in the life of one of your characters.
For a beautiful example, read Jervis’s blog entry The Next Rank, about a ritual that saw him through his years in the military.
