Who am I, and what is it that give this identity to this daily life person that I know as me ? Should I say that I'm "John the taxi" driver or "John the teacher" or "John the neigbour", or what should I say ? What is that or those specific properties that gives John the identity of the person John ? Could it actually be that he/I actually do not have an identity, and that he/I is just "another John" ? What is then "identity" ?
