May I make a suggestion?
It is sort of a Cognitive Behavioral approach to FF.
Next time you do FF, do not try to crush it. Just ride it with a 90-95% effort and allow yourself the possibility of failure. Keep doing FF in that manner until you feel comfortable, and then you can up the effort.
The very first time I did FF (as part of my free trial), I pushed too hard, and got really angry when during the MAP session the words to the effect of “you should try harder” came on the screen. I stopped right there and told myself I was never going to do a FF or Sufferfest again.
I took a day’s rest, did the FF again, and as Paul Harvey used to say, “and now you know the rest of the story.”
