“Success is an exact science if you create all the
conditions for it, you will get the result”
Oscar Wilde
So, I argue that the concept of "success" can be correlated with the activities of completely different people of different social and material status. In principle, all people can be divided into two categories: leaders and performers. Both can be successful. But if the leader has success or failure, it is clearly expressed then the performer is not so clear and unambiguous. However, there are common criteria for all success.
