Where did we learn to be afraid of making mistakes?

Sri Sri: There are many people who have no fear of making mistakes. Many students who have no fear, drop out of school and are involved in violence. Recent statistics reveal that as many as 30% of the children in North America are resorting to some sort of violence. This is a very big number. They resort to violence because they are not afraid of making mistakes. There must also be another 30% who are afraid to make mistakes, who are not interested in taking the risk and who shy away. Ideally we need to keep a balance. We are afraid of making mistakes because of the consequences, because we think we will be punished or the consequences will be very bad. Often those who have been punished several times are no longer afraid of the consequences.
You cannot totally eliminate fear, nor should we. Fear is like salt in the food, it keeps one on his toes. Fear keeps one’s feet on the ground, but fear is essential to some degree only. Life salt in the food, if there is too much salt, the food is not consumable, but you cannot eat the food without any salt. A little bit of fear is essential in the process of growth. Nature has built you like that. You drive on the right side of the road (in US) because of the fear you would get in to an accident. You walk on the sidewalk, you drive only when there is green light. These actions happen out of fear. If you are totally without fear, you could do anything and violate all the laws. Laws are always followed with a pinch of fear, and it is not a bad thing, but if there is too much fear, then it cannot be helpful. You have to keep a degree of fear like a little bit of salt in the food.
