In my humble opinion, the two most powerful tools available for overcoming procrastination are the Mental Toughness and Productivity Engineering programs, both done by Neil Fiore, Ph.D., bestselling procrastination book author and top authority in the field. There will be soon a large review of these, until then you can go visit the Hypnosis Network to find more details on your own. Don't be put off by the fact that they are hypnosis programs - in fact you will soon discover that maybe your prejudices about what you have considered to be hypnosis might have been simply wrong and off base. Not speaking about the fact that Neil Fiore, the author, is highly acclaimed for his book and work he has done in the years for procrastinators.
