 Today, I am going to discuss general principles of human development. Principles are very much important to understand the growth and development of human beings. And these principles actually provide the framework for every human to understand the rate and the achievements and the growth's fluency to just see that what pattern a human being is following. So these principles are very, very much important to see that whether the human being is proceeding well or whatever what factors are actually influencing the human beings growth and development. So the principle is number four, individual differences in the development process. So we all know that humans are different from each other and no one is equal to each other and everybody behaves differently. Even two brothers and sisters, they are different and how they are different. Everybody is different by intelligence, everybody is different by attitudes, everybody is different in behavior and why these humans are different because God has created human beings differently and God has actually given the abilities to human beings differently and two brothers are not same and two sisters are not same. So today we can say that intelligence-wise, humans are different, similarly, their specific and general abilities are different, similarly, even their behavioral patterns are different. Now this difference is a hereditary factor and environmental factor. So with these differences, human beings survive. Now we have to accept people with these differences because we can't say that two people, if one brother is an engineer or a doctor, then the other should also be like that because intelligence and aptitude also come with their own difference. So according to the intelligence and aptitude of each person, the behavior of their life is different. That's why it is wrong to say that expectations are wrong. Parents and teachers think that every child is an A grader. Every child cannot be an A grader because he has his own choice, his own liking and disliking. His choice of profession, his choice of subject is according to his aptitude. So these differences, when we don't deal with them properly, then there are big problems for children. Even at home, when parents deal with their children differently, it means that one person has a lot of love and the other person has a lot of attention because of which jealousy is created and children do not come into positive relations with their siblings. That's why the principle of development of individual differences is very important. Parents should also provide guidance and teachers should also provide guidance that in one classroom, Allah is Divyaan, he has created very intelligent and very little intelligence. Whereas the average students and average human beings have been created in a large number to run the whole system of this universe. If all the images were there, then it would be difficult to run the system of this universe. Similarly, if the less images were there, then it would be difficult to run the system of this universe. That's why the Divyaan of Allah is very great and according to that, all the universes are taking advantage of all the abilities of these people. So now it is very important to understand the individual differences for a teacher in the classroom. If a child is not able to pick up what you are saying, and the rest is picking up 50% students, then you will have to see if there is a problem of intelligence, if there is a physical disability, or if there are personal factors such as self-esteem, confidence and shyness. These things are not being discussed. This also comes in your individual differences, that one brother is very bold and the other brother is very shy. These two sisters are different in their attitude, in their psychological well-being. So what we are talking about here is the individual differences in the development process. So these biological and environmental factors decide how to deal with the differences. The hereditary differences come with the children, with the parents, but the environmental factors are in our hands. We can somehow change them and handle our differences well. After this, development depends on maturation and learning. As a person grows, his growth comes from immaturity to maturity, and in the same way, he learns from his environment through his experiences. So two things are very important here in development. One is maturation and also the learning of the child. One is your hereditary or natural growth, maturation, physical upbringing, and the environment that is taking you to the next level, is that your personal experiences are good or bad. Because of that, the way you respond to society, you learn in the same way. For example, if you have deceived a person, then this is your learning. You will not repeat that mistake again, and the next time, you will show more maturity. And after that, maturation is your foundation, your physical growth, in addition to that, your development, your emotional development is also happening, along with age, along with time, you learn from the other people, from your environment through society. So development depends on maturation and learning through environment, which you learn through your experiences. So child's environment and the learning that occurs as a result of the child's experiences, these experiences are different from yours. You learn from your peers, you learn from your neighborhood, you learn from your home, you learn from your teacher, you model them, you follow them. And similarly, when you come to school from your different environment, your peers, your friends, they socialize with you. So as a result of socialization, your behavior changes. And with all these processes, a child learns, along with learning, his maturation happens and he leaves his maturity, and goes on to his life.
