A loss in trading is not a loss
Most traders take losses and get frustrated why their trading strategy is not working.
It may hard now, but in years, you will be shock at yourself because both the pre-mature and mature traders will be under your tutelage for more knowledge(learning of tips and strategy) and they will be equally recognize you as their MASTER in trading space.
I get your point that a loss in trading isn't a loss but I try to understand that when it becomes a continuous process that's when its describe as a loss. You know some people don't actually take it to themselves that it isn't a loss but instead a learning process and that's because they have different reasons of which they tend to trade but nevertheless what makes a trader successful is being able to understand this process and see it as an opportunity for growth.
