Losing is just the normal thing in trading. You can't always succeed unless you are God. but, the most important thing is that you have to learn from those mistakes and never repeat.
yeah.. and all those who think that "losing" is just a bad thing, are the ones who are always going to have incredible losses while they are trading.. This is the truth, you really need to fait at some point in order to be a succesfull trader.
I think the fear of losses is natural things mate, everyone wants to be rich and risk their wealth to get rich from trading, that's why they are afraid of losing trades because it will certainly harm them, but you're right that a great trader should be able to manage their fears so as not to have a bad influence on him, you should be able to keep your fears out of panic,,
