We know that the market is dynamic,as in it changes constantly,and as such,an investor who isn't careful enough to know when he is investing will fall in to heart problems or emotional trauma as a result of a massive fall in value,that is why it is important to condition your mind in a way that you won't get heart failure when you are at the loosing end.
Every investor knows there is risk in the game,and taking the risk is what shows you are ready to eradicate poverty from your life.
It's true that we need to take risks to get anywhere in life. There is nothing free when it comes to trading and investing. Without risks is only our bank account that provides no interest or a maximum of 0.5%. Comparing that to 10% inflation is awful. We need to take risks to make decent returns, but this doesn't mean that we should be taking any risks. A good trader can distinguish between the risks that are worth taking and the risks to avoid. Running after the highest possible risk there are is not going to make us rich. It's like only betting on 0 in roulette. The risk we take needs to be in relation to our capital and our expected profits. If we don't have enough capital to sustain a loss we are in big trouble.
