If you know someone who’s still living with their parents, show them they shouldn’t despair by giving them one of these biographies. Several of the most talented writers and artists we know of lived at home for years before going on to produce the work that made them famous. Even Henry David Thoreau, author of “Self-Reliance,” relied on his mother for home-cooked meals while he was living in his cabin at Walden Pond. Perhaps for your friend, too, it’s only a matter of time.
