ReallyGoodIdeas has some...really good ideas

, and I'd also say there really isn't a way to do EFT "wrong" such that it does anything counter to your efforts. It mostly removes the emotional charge from whatever you use it on, a problem, thought, behavior, a memory etc.
I've used it on procrastination before and it's helped. I used to always get this feeling of dread whenever I approached something that I felt I had to do, such as some project being due. It was like some kind of resistance pushing me away from whatever I had to do. Recently I encountered one of these familiar situations and decided it was about time I worked on it with EFT. It was quite interesting to find out how many different thoughts/beliefs were contributing to my procrastination such as perfectionism, fear of failure, feeling I needed to be entertained all the time, that I couldn't do it right or that I didn't know how to do it. It took a good bit of rewording of phrases I used to get some significant results. While I don't have perfect motivation now, the anxious feeling has lost a lot of power over me, and I can usually look past it and get to doing what I want done. It's a big improvement for some things, but for others I still lack some motivation.
Getting the wording to really nail an issue can take some time, a lot of it is just experimenting with saying whatever comes to mind when thinking about procrastination, such as "I hate this" "I should've done this earlier" or "if I don't do this it'll be horrible", and then after those are worked on, usually related thoughts come to the surface which can then be used. Also what helped me was reading through the different cases/stories on the EFT website, good examples of wording there.
