When a thought arises in the mind, you can ask yourself "where does it come from?". I imagine that there is a subtle area in the mind where the seeds of thoughts (idea's) take shape. It is invisible what happens in this subtle area. Only when the thought already has some form it becomes visible in the conscious mind.
If you look at a new chessposition, there seems to be a gentle rain of thoughts about the position. You need your discrimination to decide which thought is good in the given position and which thought is bad. So one area where you can work on is your ability of discrimination. But the non-rethoric question is:
"Can you have an indirect influence on what happens in that subtle area of the mind where the conception of thoughts takes place so that the quality of the gentle rain of thoughts improves?"
