One of the most famous sidetracks is pride.  Having overcome an over-eating problem or a drinking problem or an addiction or bad habit of one sort or another, instead of being humbly thankful for one’s new life, the reformed person becomes puffed up at his or her success.  In such cases, the person may be worse off than before, from a spiritual perspective.  And this pride can take on a whole range of hues and tones so that it does not appear as pride, so that it seems to be nothing more than so-called self-esteam or a new passion to be better and better at fitness, or healthy eating or even preaching the evils of self indulgence.  Pride hides behind many masks.
