I think a great deal about the difference between routine and ritual as a special case of our more general and generally trying quest for balance — ripped asunder by the contrary longings for control and whimsy, we routinize daily life in order to make its inherent chaos more manageable, then ritualize it in order to imbue its mundanity with magic, which by definition violates the predictable laws of the universe.
I like this definition. Rituals can help lead to habits that support your creative practice. Even creativity needs practice and ritual can set your intention and determination toward fulfilling your goal.

To really develop a habit for creative practice, you need a regular ritual. For example, Stephen King (a prolific and creative writer) sits down each morning to write for a few hours. He compares the process of getting ready to write to the ritual of getting ready to go to sleep.
Rituals don’t have to be elaborate. They can be as simple as my ritual of cleaning my working space before I begin a new book.
