From your post it's hard to see what is wrong, but I do see you have a goal. For that goal I suggest you a look at the decisive action course. It has the appropriate paraliminals and the coaching how to use the paraliminals for reaching your goals.
http://www.learningstrategies.com/DecisiveAction/Home.html The paraliminals that would probably help most are already part of that course. With the coaching sessions how to use each tape and a manual that helps you to focus on your goal.
If you only want to try one paraliminal I suggest Sales Leap. It is actually a self confidence building tape. When you consider how much confidence a sales person need...
Other options are
New Behaviour Generator, -develop the desired behaviours.
Self Esteem supercharger - If you feel you don't deserve to be successful as a salesperson. (One possible reason for procastionation).
Instantaneous Personal Magnetism - project the image that allows people to enjoy your presence. (If you feel uncomfortable around people)
Get Around To It - Get a boost for taking action.
All the paraliminals are good. If you only want to buy one or two you'll need to explore and find out your reasons for not taking action and trust your instinct. Each paraliminal has a webpage explaining in more detail what it is useful for. If you have a read of the ones I suggested you'll probably discover which area you need to focus on.
