I think for me the line is between the continuum and the moment. In terms of the continuum of one's life it's good to own your own crap, but that doesn't mean it has to engulf every single waking moment of your life.

It's like happiness. Am I happy with my life? Yes. Am I happy every single waking moment of my life. No.

Owning your own crap is about acknowledging that there will be crap from time to time, so there's no need to be too hard on yourself.
