How is Pride the enemy of Hope?

The Bible has much to say about hope, especially in Romans chapter 8. The Old Testament has much to say about pride, which God hates (Proverbs 8:14, for example). As for despair, Christians are encouraged not to despair even when perplexed (2 Corinthians 4:8). ___I can readily understand how despair can destroy hope, but how would pride be the enemy of hope?___ I found this expression in a novel set in the republic of Ireland, where the main characters are educated by Catholic nuns. Pride and despair are both viewed as sins. Initially, I would like to explore the views of Catholics to establish if this is part of their beliefs. ***In what way, spiritually speaking, are pride and despair the twin enemies of hope?***
