Hunches are more powerful/accurate than conscious decision making.
That doesn't mean that your hunches will necessarily be accurate; just that they will be more accurate on average than choices made consciously.
How many of us traders have entered a discretionary trade knowing on some level it was going to reverse on us? Common, right?
Someone very in tune with his hunches is billionaire speculator George Soros. And according to his son, George himself is completely unaware of the process.
To become that good at speculating, one needs to be free of a whole host of potential fears, eg. fear of failure, fear of success, fear of being wrong, etc.
