Do you ever feel like you can be honestly you in any situation?
There is the perceived 'you' that is the projection of who you are from other people. In other words, there is the 'you' who people think you are as opposed to who you know you really are.
Job interviews are a good example of this. We are trying to sell ourselves and project the very best (or what we think is the very best!) of ourselves so that we might get the job we want, and there is nothing wrong with this. If we were honestly and actually our full selves in a job interview it would most likely break all kinds of social etiquette!
But there is a point that we all need to be a bit more honest about who we are rather than trying to live up to a certain expectation that we have placed upon ourselves or that others have put upon us.
