Trading gives you money, in order to to protect your money risk management is paramount.
How are you going to manage the risks when you only talk about profits? Profits and losses are both a part of the trading system. You need to have experience in both in order to learn the whole system. What are losses? Mistakes? Miscalculations? Emotions? Whatever it is, if that happens, we need to learn from it. And how can you only focus on profits while even the pros are making loss now and then?
We need to experience both and then create a mindset which will not get effected by such things. This will give us the best advantage in trading because only then we can control our emotions.
