If you ever think there is no internal work to do on the self that is yours with this incarnation, get out your natal chart and look at each opposition and square. See if you’ve overcome those aspects of your character.
If you are ever low in self-esteem, get that natal chart again and look at each of your trines and sextiles.
Where are the aspects neutral, places where you have to consciously decide to be a moral person?
At the conjunctions of planets in your natal chart.
