If you are an investor, you must be smart, and wise and never be carried by your emotions. It is simply because making emotional decisions in investment is a big mistake. You might experience fear and greed that may drive you to impulsive decisions. You might also have a gut feeling about biases such as overconfidence that could lead people to overestimate the ability to make accurate investment predictions. As an investor, you have to consider people's feelings and that your future relies on them so never give them room to think that you are not good at investment. They can predict your actions that may affect your investment.
