Be yourself everyone else is already taken(Будь собой, все остальные роли уже заняты) что по вашему это значит?​

These are very clever words that cover a huge meaning.We should not be under someone's masks, pretending to be someone, some "actor" in life.You need to be yourself, you don't need to imitate someone,you will feel out of yourself,you will feel uncomfortable.This is not right, you should try to be open,you should not be afraid to be yourself.After all, our "true" face is more pleasant than someone else's.
