You must always try harder, but you never cross the finish line. You seem to merely go in circles. Or perhaps it would be better to say you go in a spiral, as in a downward spiral. Life is a perpetual treadmill. You work hard and strive, but you never arrive.
Life is hard work and frustration with little or no satisfaction.
The overactive conscience produces constant self-monitoring. You are constantly asking if you are being an asset to other people and to God. You are constantly evaluating and even doubting your performance. And you never allow yourself to be a liability to the group or to any particular individual. An overactive conscience involves a lifelong ordeal in which you attempt to pass a demanding test and thus reveal your worth.
