When I was 45, I had my son tested for ADHD. Looking over his shoulder, I read the questionnaire. “Don’t finish projects you start,” “difficulty sustaining attention,” “struggle to get organized,” “avoid, dislike or are reluctant to engage in tasks that require sustained mental effort,” -- these were characteristics of a diagnosable mental illness that could be treated?? I got distracted from helping my son take the quiz because a light bulb had gone off in my head about so many of my own lifelong struggles.
