First of all I resentthe term. As far as I'm concerned most people have Attention Surplus Disorder. As far as I can see,many people who don't have ADD are charter members of the Congenitally Boring. But anyway , be that as it may, there is thissyndrome called ADD or ADHD, depending on what book you read. Some people say the so-called syndrome doesn't evenexist, but believe me, it does.
Many metaphors come to mind to describeit.
It's like driving in the rain with bad windshield wipers. Or,it's like trying to build a house of cards in a dust storm. You have tobuild a structure to protect yourself from the wind before you can evenstart on the cards. In other ways it's like being super-charged all the time. Because you're trying really hard.
