From my trading experience, I have come to realize that experience is the best teacher because if you continue to look for any secret about like one of my friend is to tell me so shall you continue to lose your money in trading. Try as much as possible to learn from your mistake and other people's mistake, in doing that your trading skill will improve significantly.
At first it will be hard, then as we push through we will eventually see how profitable trading is depending on our skills, strategies and knowledge. We will be able to see too that we learn and we gain without us noticing that we already get the fruit of our labor by being dedicated to be successful.
