In trading, emotions are the worst enemy. They can make you take bad decisions and lose a lot of money.
A trader is not looking for emotions, a trader is looking to make money.
If you are looking for emotions, go for extreme sports
If trading causes you strong emotions, it means trading is not for you.
Price increases and decreases must not have an emotional impact on you, otherwise it may cost you a lot of money..

I do agree because emotion will be bothering you to make wise decisions. And as you can't make a decision wisely, it may led to you losing what you have and will be a hindrance to reach your goal of earning. Maybe you should learn how to control and handle emotions so that it will not cause any negative things while you are in the process of making money.
