A human is not a robot. Panic attacks because of being afraid to lose all the money is a common case. But a trading strategy does not have to constitute only panic and constant thinking about it otherwise, it is not a trading but damages. To be less afraid to trade it is possibly better to reduce a capital for trading.
Yeah you are right. Every person in this world will feel panic some times and somewhere in his life. When a person start trading, panic starts with this. He would always think about the market situation and the price. He will search for the reasons for the price ups and downs, because he is doing business. All businesses in the world are not without panic and fear.
