A sense of superiority over others, excessive admiration of self, and failure to appreciate others. Pride is the original and most serious of these 7 vices, and is the source of all sins.
You need to learn how to manage
your instinct for EMOTIONAL SECURITY,
your needs for LOVE and ACCEPTANCE,
and your fear of REJECTION.

To resist talking so much about yourself,
to avoid putting others down by raising them up,
to shift your attention from yourself towards others.
Is this something that you think you can begin working on?
Is there someone that you can begin showing this change to?
