One of the advantages of humility is that it enables us to learn from everyone. A proud person cannot learn from other people because he feels he already knows better than they. On the other hand, a humble person who respects everyone and recognizes that they may even be emanations of Buddha has the openness of mind to learn from everyone and every situation.
