what do you know about yourself? rather; what do you think you know?
characteristics, attributes, talents... were they ascribed to you by you? or by those around you?
do you feel it in your heart? does your brain tell you they are real? do you believe it? do you question it?
have you ever bored a hole into your own skull just to see what poured out? to see what was actually in there?
perhaps someone did you the favor to spare you of doing it yourself? the stuff that comes out, however, is always different when it is done by the hands of another.
