The idea of ignorance is bliss can only go so far! It reaches the point of self delusion or self B.S. This is where the f-word comes in--starts with "f " and ends with "ck"--that dirty word feedback. Practice with a test target every day. I spin around with my eyes and ears covered then toss the test target, spin around a bit more so I don't get any reference point. Then locate it or at least mark your lines so you can see where you went right and where you went wrong. Put it this way, guessing if you got it right or wrong without getting any feedback is about as phony as you can get. And that's what's happening around here. Might as well throw a coin into the wishing well or wish on a falling star. Hardly can even call that dowsing, sort of like the joke on the bathroom wall "No job is done until the paperwork is finished". You know, everyone is getting cheated.
