How Can I Identify My Root Sin?

Here are the three possible root sins: pride, vanity, and sensuality. Pride, in this sense, refers to a disordered attachment to our own excellence. The proud person tends to seek meaning and fulfillment in their own achievements and conquests. Vanity is a disordered attachment to the approval of other people. The vain person tends to seek meaning and fulfillment in being appreciated or liked by other people. Sensuality is a disordered attachment to comfort, ease, and pleasure. The sensual person tends to seek meaning and fulfillment in taking it easy and simply enjoying life.
