When my 11-year-old was diagnosed with attention deficit hyperactivity disorder (ADHD), I was shocked. Determined to prove he was \u201cjust fine\u201d I learned as much as I could, voraciously devouring books and articles. Right away I realized, \u201cThis describes me!\u201d\n\nThat realization was the biggest turning point of my adult life, and it transformed how I saw myself. It made sense of why I struggled with simple tasks but managed to write and perform in 700 episodes of radio and television and countless stage shows.\n\nKids today are usually diagnosed early \u2014 teachers know what to look for \u2014 but it\u2019s estimated that 80% of adults with ADHD are undiagnosed. These people are often struggling to do things other people consider simple, routine and easy, yet capable of amazing feats when interested and engaged.
