"Don't send your characters to reform school!" pleads Sarah Ruhl in one of her essays. With titles as varied as "On lice," "On sleeping in theaters," and "Motherhood and stools (the furniture kind)," these essays are artful meditations on life in the arts and joyous jumbles of observations on everything in between. The pieces combine admonition, celebration, inquiry, jokes, assignments, entreaties, prayers, and advice: honest reflections distilled from years of working in the theater. They offer candid accounts of what it is like to be a mother and an artist, along with descriptions of how Ruhl's children's dreams, jokes, and songs work themselves into her writing. 100 Essays I Don't Have Time to Write is not just a book about the theater. It is a map of a very particular artistic sensibility and a guide for anyone who has chosen an artist's life.
