Fear helps us to know when to fight or take a flight. Enough, often when we experience danger, our min will tell us if we should fight or flee from that situation. Fear acts like an instinct, which will tell us what our next move should or could be.
Fear also allows us to be humble. When we know who we're going up against, there is a sense or a feeling of fear. Especially when we're facing our authorities. Like when a worker is talking to his employer.
Fear also helps us to learn from our mistakes. When we make a mistake and have to face the consequences (which is often unpleasant), we will feel fear. When being put in the same situation again, we will think twice about our actions. By thinking twice in the situation to not make th same mistakes again, we can imply that fear is present. Because of he fear of the consequences that we have, it lets us carry out the tasks as accurately as possible.
Fear is also needed for us to take necessary risks that will allow us to go further. Without fear, we will not take ricks without careful consideration. That situation would seem very superficial and mundane.
However, if we fear too much, it would not be beneficial to us at all. We will e too scared to take any risks. If a businessman wants to start or open up a business and he does not take the risk, he would not have started at all. Business is like a game of risk. There is no confirmed profitable business.
At the same time, if we do not have fear at all, we will become rebellious towards future threats, which might even cause one's failure.
