Reasons for being envious

Well, there are a lot of reasons for people to be envied to other people. Those reasons are of different nature but they always root to the childhood. As most of mental abnormalities and diseases the feeling of envy takes its start from the very childhood of people. They are our parents who want us to be happy and they are also our parents who prevent us to be happy.
See, most parents use several common methods in order to make their children do things they want them to do. It is common for parents to provide some kind of grant-system for things children do. It is like they show their children that everything good will be payed back for them. They provide their children with money or other stuff for good things they do.
But there are also parents who consider it is wrong to grant children with money or something like that and they use another method. This is the method that later make children envious people. It is when parents say their children that they are bad and they compare them to some genius children next door or something like that.
Children become thirsty for all those merits other kids have because they want their parents were proud of them. And later, this feeling of being good enough develops into envy and inferiority complex. See, a reason for envy is feeling that other people are better and they have more.
