Well…I thought that this question can go to bed for a while. I was wrong. I hope you ask this question from time to time. I think sometimes I ask this too much; I ask allot of questions and sometimes too much. In some circles this is called analysis paralysis. Keep questioning and you come to a point where the questions bog you down. Stuck in the quicksand and the more you struggle the more you sink in.
Yet, at the other end of the spectrum I believe there are more people that don’t make a concentrated effort to “know thyself” according to the ancient Greek aphorism. The challenge is to ask questions about yourself; allow yourself to be challenged about your paradigm and the underlying assumptions – “an unexamined life is not worth living” – Socrates (picture of dead guy above).
