Hey Viktor,
glad to hear you have your enthusiasm in trading back. Try to ignore the trading results you had before. I can share with you that most of the students joining the Academy is after having losses. Nearly everyone starts trading without any kind of education.
And actually the enthusiasm should be used in hard work with EA Studio and the Expert Advisors and not in trading. Emotions should not be there in trading! Trading automated EA Forex is one of the key points to ignore the emotions.
