Having ADD [or ADHD] makes life paradoxical. You can superfocus sometimes, but also space out when you least mean to. You can radiate confidence and also feel as insecure as a cat in a kennel. You can perform at the highest level, feeling incompetent as you do so. You can be loved by so many, but feel as if no one really likes you. You can absolutely, totally intend to do something, then forget to do it. You can have the greatest ideas in the world, but feel as if you can’t accomplish a thing.
