 Types of individual differences, so individual differences are very normal and everybody has differences. Anybody has differences in liking, disliking, everybody has differences in choices, everybody has differences in intelligence, everybody has differences in attitude, aptitude. Even, you know, they have differences of eating of different foods and they have differences of liking their clothes, their shoes and colors even. So these differences are called normal differences because these differences are not weird or strange that if somebody is choosing something else and the other person is choosing something else, then these differences are called normal and God has created all human beings differently. So we should accept these differences and what are the reasons behind to make people different? So these reasons or these factors are many and multiple. So we will discuss today that how many these factors are affecting the differences in personalities of human. So first of all, if we talk about heredity and environment, then heredity difference is a person who brings his birth with his parents in his genes. Heredity and qualities are different because every parent's genes are different. Similarly, human's genes are different, so their heredity and qualities are different. But two brothers and sisters also come into this world with different qualities. And despite being a parent, their choices and liking and personality can be different. This is also a normal factor. Apart from this, the influence on personality, caste, race and nation, that is our environmental factors, if we believe in the caste system, then our caste-wise family-raising attitudes are different. Our home environment is different. And all these things that raise up the personality of a person is done differently. So when they are brought up differently, then automatically the differences come. So these differences come because of their environment's enforces. After that, temperament, emotional stability, everybody has different attitudes and aptitudes by birth or through environment. If different people at one home are getting different environment, they are getting different attitude and they are getting different environment from their parent's side. And if the elder son is getting more attention, the middle son is getting lower attention and the youngest is not getting as much attention, then these things will create difference in their personalities. After that, there is a parental conflict. If parents fight over each other, then the environment is not peaceful. The effect of that is very high on the children's personalities. So one child is coming from a peaceful environment, the other child is coming from a conflict environment. This will also bring a difference in their personality. After that, the individual has different goals, different intros, different emotional problems and different abilities. One child wants to be a pilot, other child wants to be a doctor, other child wants to be a teacher or engineer or lawyer. So everybody has different choices. So these choices can be through environment and these choices can be their natural abilities and aptitudes because a person has two types of intelligence, the general intelligence, general aptitude and the specific aptitude. And specific aptitude means that he has naturally aptitude to become an artist or he has natural ability to become a musician or he has natural ability to become an actor. So some abilities are natural and you take them from your parents' genes because of which you are different from other people. After that, if you get the same environment that flourishes your abilities then it becomes very easy for you to achieve your goals. So the choices are different because every child has different abilities. Now if a father is a doctor, it is not necessary that a child also becomes a doctor. His aptitude or attitude is towards becoming an artist. So he is towards becoming an artist. He can become a painter. We say that he is born painter, born actor. So all these forces that are of your environment and heredity, all these forces bring a difference in the personality of all human beings and people behave always differently in the environment. So we should not criticize them for getting these differences but we should appreciate these differences because a man can work well with these differences or with innate abilities or environmental different forces to control all these forces. So these individual differences basically create beauty in the world or environment because the same thing will not attract you but the unique things they will always attract humans.
