" Difficulty getting organized. A major problem for most adults with ADD. Without the structure of school, without parents around to get things organized for him or her, the adult may stagger under the organizational demands of everyday life. The supposed “little things” may mount up to create huge obstacles. For the want of a proverbial nail—a missed appointment, a lost check, a forgotten deadline—their kingdom may be lost. "
