Ace,
You have to teach your subconscious what a yes answer and a no answer is. I did it mentally by reviewing what I expected for a yes, wires crossed, and a no, wires pointing away from each other. You can also, with wires in hand, look at them and say this is a yes and make them cross and this is a no and make them swing away.
Google ?Letters to Robin?. Is is a free, short book about dousing that explains a lot.
Before you ask a question about a subject, ask ?May I?, then ?Can I? and ?Should I?. If you get a yes for all 3 then ask the question or questions about that subject.
Have fun.
Jim
