Hello James1,
I personally recommend the 'Get Around To It' Paraliminal tape. I use this myself and I get immediate results when I use it. It breaks through the logjam by helping you to reset your priorities and reassures you of your ability to take action and make decisions.
There have been other posts in the DF on this topic that are helpful as well. Do a search for 'procrastination.'
One nugget of truth that I have learned and have been facing up to is that a lot of procrastination is rooted in a sense of shame and guilt. (For the more acute procrastinators such as myself, anyway.)
