Your mistake is that you are letting your emotions influence your decisions. There is nothing wrong with that when it comes to making personal choices such as choosing a career, partner, or house. 

When it comes to the impersonal world of trading, this is a terrible strategy.  Emotions are predictable is that is precisely why more experienced traders are making money off of you.

To be successful in the trading game, you need to be an ice cold bastard.  Few people have what it takes emotionally and the ones who don't should stay away from it.
