This essentially means that in being a waiter, grocer, etc., one must believe that their social role is equivalent to their human existence. Living a life defined by one's occupation, social, racial, or economic class, is the very essence of "bad faith", the condition in which people cannot transcend their situations in order to realize what they must be (human) and what they are not (waiter, grocer, etc.). It is also essential for an existent to understand that negation allows the self to enter what Sartre calls the "great human stream". The great human stream arises from a singular realization that nothingness is a state of mind in which we can become anything, in reference to our situation, that we desire.
