Procrastination and ADD (Attention Deficit Disorder)

Have you ever been suspicious of yourself being affected by ADD? do you have problem to concentrate on tasks and how long is your focus span? What about procrastination, do you have a long list of things to do, which you just ignore and from time to time, remind yourself of consequences if not done?

It is either ADD or I am not tuned into what I am doing to earn my living,
