Envy or rivalry?

As it was said before there are different kinds of envy and each of those kinds are of different nature. Any feeling we have makes us do things and the nature of those things we do under influence of certain feelings depends on the feeling. So, we know that the best envy we have in this world is an impulsive envy. It is the envy that impulses people do something.
This is the kind of envy that is very alike the rivalry. So, it is the envy that makes people think that sky is the limit. The rivalry appears as a result of an active envy. It is when one sees the success another managed to gain and instead of being envy and mad about that success he realizes that if one managed to gain it than it is possible for him to gain it.
In other words, people see other successful people and they realize that they are of the same kind and so it is possible for everyone to gain a success and respect and so on and so forth. Rivalry never makes people mad and never makes people hate those who are more successful. Rivalry makes people apply efforts in order to reach the same level and even higher.
See, the envy is of great help sometimes. Well, it is not actually the envy of great help but the result of it. The rivalry is a result of envy. It rare happens that envy develops into rivalry though it does happen and it is great when one is able to stop envying and to do things in order to reach the same level – this is a base for progress of people.
