I think most of us want to be good, but in practice, I expect that we don't live up to our own expectations - unless we are wholly narcissistic and have a view where we are infallible.
We all have dream in the beginning. However, as time goes on, life forces us to feel enough with what we have had/achieved in time. I think many of us don't live up to our own expectations.
Constant failures - perhaps it is good to be wholly self-consumed and living in an illusion of infallibility.
