I agree.
My point is, even when you gain certainty, you'll have control over the feelings.
Many people think that if you just control the feelings, then you are going to be a fantastic trader. Not so. You have to understand how to trade.
Even having a fantastic system is not enough. You have to understand.
My post on requotes is a good example of one of these things, for me. It's true for me, and from now on, there'll be no emotions when I'm confronted with that thing, although it might not be true to everybody else.
