That's right. Fear is the worst enemy of traders because they often can't reveal their potential because of a strong fear, especially when they had unpleasant xperience in the past, for example, if they twice lost their deposits, then there is a very little amount of chances that they would enter trading again. However, the market loves those traders who don't give up. Of course, sometimes it's really difficult to change your worldview and opinion concerning trading, nevertheless all those traders who are successful, they came to this success due to such situations.
Fear indeed become the most enemy from own selves, besides fear also greedy, sometimes trader they still want more although on the day target already achieved, or they become overconfidence when taking a look the market seems will giving accurate trading analysis and then increasing volume trading, but usually when trader face with the big loss they just been realized if already make a mistake.,
