ADD and time management!

So I seriously need to work better on my time management skills. I need to work on routines. The problem with being ADD is that I have trouble with time management, but the great thing about ADD is that I can do 20 things at the same time and get them all done...just at the last minute, and not usually in a routine. I have spurts of accomplishing a great amount of things and then nothing! It works for creativity, and being involved in lots of things, but I really need a secretary!
