No...
I don't even talk to myself verbally or mentally.
It's just a mental distraction. I am going to rationalize why...
First, I have a pretty good experience, skill and understanding of speedreading. So I'll write my thoughts based on that...
1. We are taught by verbal expressions. First, when we are born, we learn from our other senses and from pure impression and curiosity. After a while, because of how we communicate, we start thinking and expressing thoughts with others by verbal communications.
Don't you talk to yourself when you think? Don't you re-read what you see when you read something? That's what I'm talking about. We really don't have to re-phrase expressions to understand it, it's just the way we were taught.
2. Verbal expressions in all terms are extremely influential. Look at Tim Robbins, XXX-cybernetics (psycho-cybernetics??), hynosys, or Auto-suggestion. When a person says something in there head or even more verbally, that thought sticks to them. How much you try it does in some sort of way.
Also, verbal expression is one of primary source of learning for most people. Yes visual expression is also large but most people can't do it well. (again... how you read? Unless, you're a speedreader... though speedreading is not the only answer) That's one reason I respect and think woman makes a good trader because they are expressive but also master impressionists and have over the top intuition compared to men... in general.
Well, that's the reason for my thoughts. Try blanking what you think in your head and try trading. It's very interesting to see what happens... or even more start looking at a blank chart and blanking your head.... start adding indicators to your computer screen see when you start to get intuition or even, no intuition.
