My husband is a genius in several areas, primarily mathematics and physics. He talks to himself--yes, in public, in our home, all the time he has to keep speaking just under his breath as a way to stabilize his brain. Sometimes he is repeating a conversation or preparing for one. Sometimes it is an argument. But it keeps him grounded. Otherwise, his head would float up into a sky of numbers, like if it were a hot-air balloon and his talking to himself--that is the sandbags that keep him grounded. So your self talk is probably some kind of coping mechanism or stress relief. As for myself, I hear voices from the past telling me that crap; that is sad. It might be good for me to argue with those voices. shipping
