Some of the simplest inventions can be the most successful and profitable efforts inventors can develop. For examples I think of Joy Mangano and her reinvention of the floor mop, which made her famous and in more recent years her reinvention of the closet hanger, who knew it had to be invented in a better way. For her very entertaining story read her book Inventing Joy or watch the movie Joy starring Jennifer Lawrence. Look around the house and yard to see what you might invent – again.
