People who have excessive fear in investing will never invest properly. If an investor tries to make an investment decision with excess fear, he still cannot make the right decision because of his fear. There will always be a fear in his mind that if he loses all his money after investing or he will worry more if his investment does not give him the desired profit. Another downside for an investor who is overly fearful is that a slight change in the market will put him under a lot of stress and he will make wrong decisions, so he should get rid of his fear before investing. Over greed is never good, one should always have limited expectations of oneself. When one's expectations are fulfilled then there is no need to make extra profit. Avoiding excessive greed is good for an investor if he has set his own goals in investing.
