It seems to me that the knowing of oneself is of the greatest importance. But the knowing must be relative to age, experience and introspection. At twenty I thought I knew myself, but I was only on the road. I was beginning to process options and with the beginning of each new viewpoint or project I felt like this is it, this is who I am. Then when I moved on to something else I thought, well that was not really me, but this is. I was painting some then, watercolor and ink mostly. I was reading everthing still, without much descrmination and with a solid preference for fiction. I went to church and over a number of years filled various roles in that context, I taught Sunday School, served on commitees, sang in the choir.
About 25 I stopped painting, I did not believe that I would ever attain enough technical skill to be anything but a Sunday painter. Over the next years I went to school, changed religious focus, started reading non-fiction in earnest. Then I entered the adult workforce in a serious sort of way and only read legal and religious material. Those were happy years that gave me a break from feeling like a failure. Then at about 33 I had mastered my work and needed more, again I shifted religious focus and added photography and design to my life.
At forty I started painting again. My religious focus changed again and I started reading fiction again in small doses. At forty five I was still painting, no longer feeling that I could not master technique, reading deeply still in design, and with a modified, though not totally changed religious focus.
Now, the modified religious focus is pretty solid, the painting is going very well, the reading is mostly art.
So at twenty I would have said "I am an artist, I am a liberal christian, I read".
At twenty five or so I would have said "I am a christian, I study, I read".
Then at twenty nine I wiould have said "I am a paralegal, I read for my work".
At thirty three I would say "I am a photographer, I am a pagan, I read"
At forty I would say "I paint, I study color and design, I am B'nai Noch"
At forty five I would say "I am a painter, I look at and study art, I am a religous person"
Now, I say simply "I am a painter"
So, I did know what I was at each stage, but I was still learning and trying things on. Even now, I cannot say with any faith that in ten years I will still say "I am a painter". I don't see it now, but maybe then I will say "I am a sculpter" or "I write graphic novels". At twenty I did not see where I would be now, but looking back I can see how everything that came before directly formed what I am now.
