I am told to just be myself, but as much as I have practiced the impression, I am still no good at it.

All my life I had been looking for something, and everywhere I turned someone tried to tell me what it was.  I accepted their answers too, though they were often in contradiction and even self-contradictory.  I was naïve.  I was looking for myself and asking everyone except myself questions which I, and only I, could answer.  It took me a long time and much painful boomeranging of my expectations to achieve a realization everyone else appears to have been born with:  that I am nobody but myself.
