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.
Trading is a roller coaster-like ride of emotions so it will surely affect you emotionally and physically and if you are not ready for it, you might fail. If your health is being affected by your journey, you better stop for a while and focus on your health. It's fine to rest because you can come back any time. Maybe you're too eager to make a profit and already disregarding the risks. Health is more important than money.
