Your unconscious comes back to you and says, "it's ok because I calculate at a rate of tens of thousands of permutations a second and I can tell you that there are fifteen sentences that you can use. They all start with those same first four words and totally change the subject. They won't have a clue what you were going to ask them."
You go back to your unconscious and say, "thanks, but I only need one."
The unconscious comes back to you and says, "well, we have now got it down to five sentences that are perfect, and they won't even know that you were going to change the subject."
Getting frustrated and concerned now, you go back to your unconscious and scream, "I know but I only want one!"
Your unconscious comes back to you and says, "ok, ok. Calculating at thousands of permutations a second I can tell you that this is the best one."
BAM! the sentence comes out of your mouth and the other person does not have a clue about what you were going to ask them.
It took me about four minutes to type that. It takes one minute to say it, and all that happens within your brain in literally a fraction of a second. ONLY A GENIUS CAN PERFORM THAT SORT OF FUNCTION and YOU do it almost every day in one way or another.
