We know the Torah gave us a specific mitzvah - to work on our character traits, but how do I change my very basic, underlying emotional makeup? Much like as with any character trait, I didnt wake up in the morning and say, I just want to be a big, fat, arrogant buffoon. I didnt wake up and say, I would like to consider myself the most important human on the planet G-d's gift to humanity. But what can I do? Thats how I feel. Now what?

This Shmuz helps us deal with the gaavah, arrogance, as it functions in our lives.
How do I recognize if I am affected by this trait?
How do I work on this issue?

Understanding our relationship with HASHEM is the first line of defense against arrogance, and as it turns out, the sense of humility is central to all of avodas HASHEM.
