I think you are both missing an important point and underrating yourself here. You have an incredible range of talent, experience in many areas of music, etc. You have devoted a substantial part of your life to music and have thereby developed and acquired all of the above. To relegate yourself to be a jack of all trades or a blunderer [you made choices to get where you are, it was not by accident] makes no sense. Whatever you are, that is what you are. Why define it in terms of someone else's world. I think you have a great range of talent and ability.
