When you evaluate the Seven Deadlies you should always start first and foremost with how they relate to our relationship with God. God is more powerful, wiser, and kinder than we are and we should always keep Him at the center of our lives. Pride is the sin of pushing Him from that centerpoint by falsely elevating our own worth (counterpoint with sloth, the sin that pushes him from that centerpoint by denying His ability to work changes in our lives).
It is important to note, though, that Pride is not a sin of recognizing that we have worth. He clearly thinks that we do and elevating our opinion above His would itself be pride. We know that we have gifts that we are supposed to use for His glory and that others do to. Humility is not self abasement or the denial of capability or accomplishment, humility is the virtue of deferring to God and of recognizing His hand in our actions.
