Our development depends directly on our sensation of pain. The more a person suffers, the more he wants to attain, the more he feels the need to attain higher intellectual skills, and the more our mind develops.
The contrary is also true. It is possible that a person will possess fantastic inherent intellectual and analysis abilities, but if he gets everything in life without any effort, his mind will not develop, but regress. That is why it is not worth it to be so envious of rich people who live completely like beasts, because that society is on a spiritual decline. The history of our people constantly proves the efficiency of the constant search of a way to exist under impossible conditions.
