Hi everyone,
Since birth, all of us are having different sort of experiences and learning the way to live life. That is what we transfer to our next generation. Man does not know about his next second of life, whether he will be a millionaire or remain poor, happy or sad, healthy or sick etc. this is because it is impossible to know future, but there are some lessons of life that make someone to understand what will happen the next second.
Psychology of any living being can be observed easily. Take a look at the cat which walks on to your house's roof and when it sees you, it runs away. But what happens if you pour some milk or give her a little meat to eat, it will start to get familiarized with you and never leave your house in her entire life. Similarly, sometimes ignorance helps a person to get someone's attention. This is the way of life to know future by Observing human behaviour.
