Hi, for you interest, there is a good book on ADD called "Scattered" by Gabor Mate, M.D. Here's a quote from p. 16:

The restlessness coexists with long periods of procrastination. The threat of failure or the promise of reward has to be immediate for the motivation apparatus to be turned on. Without the rousing adrenaline rush of racing against time, inertia prevails.

.... On the other hand, when there is something one wants, neither patience nor procrastination exists. One has to do it, get it, have it, experience it, immediately.

One more interesting quote: Brian has ADD. He also has a dog. They take each other for daily walks. As Brian puts on his coat, hat and boots, the dog lies under the kitchen table, waiting. Brian leaves the house, and the dog doesn't move. The dog will not budge until Brian has come back into the house for the third time for key, wallet or whatever other items he has forgotten to take the 1st 2 times. The dog has learned from experience, which is more than can be said for the owner.

This may or may not be of interest, but the book is very insightful and for the person with ADD, one recognized him or herself in much of the book.
