Katherine,
Like "agape love," "pride" eludes Christian understanding because it becomes a jargon word that blurs the vital distinction between sinful pride and healthy self-esteem, a robust self-image, and justifiable pride in personal achievement. Even frequent use of the vertical pronoun need not be an indication of the wrong kind of pride. Consider Paul's holy boasting:
"If someone else thinks they have reasons to put confidence in the flesh, I have more: circumcised on the eighth day, of the people of Israel, of the tribe of Benjamin, a Hebrew of Hebrews; in regard to the law, a Pharisee; as for zeal, persecuting the church; as for righteousness based on the law, faultless. But whatever were gains to me I now consider loss for the sake of Christ. What is more, I consider everything a loss because of the surpassing worth of knowing Christ Jesus my Lord, for whose sake I have lost all things. I consider them garbage, that I may gain Christ (Philippians 3:4-8)."
It really depends on your top priorities and who gets the ultimate credit in your heart. If deep down, you consider your achievements "garbage" when considered apart from God's help and guidance in making you what you have become, then what others may consider pride is instead grateful celebration of God's grace.
