Haven't dicked around much with it yet. But one thing I can tell is that a lot of the self-hacking stuff I came up with myself over the years has been laid out in much clearer form in NLP. Always cool to get those "ah! so that's what I was doing" moments.

One thing I'm going to be experimenting with is changing my chunking and anchoring around exercise. In other words, trying to change the number of steps I perceive it to be, and the mental images and feelings it evokes when I think about it.

Something I'm currently playing around with is imagining turning down negative self-talk and dimming mental images that I don't wish to have.
