Calibration requires sensory acuity. Without being able to actually see what is there, you can never calibrate against it.
The more we see what is actually there through artists eyes, the more we can begin to tell two states apart. As we tell states apart, we can start using that information to make better decisions.
If you calibrate against like and dislike in an acquaintance, you can read their attitudes about yourself and others. But you’d never want that sort of information from bosses or spouses or business contacts, now would you…
The same idea holds for any pair of states. Good decision, poor decision; fattening food, slimming food; etc. It all relies on first seeing a difference, then deciding between the possibilities.
So, the obvious questions include whether you are seeing/hearing/feeling and whether that sensory acuity serves you well enough to distinguish states. If you’ve got those both down pat, keep up the good work. If not, it is time to change that. Of the options, I definitely recommend NLP Monthly and I’m sure you will too once you see more of what is in store for you!
