By putting yourself in a humble position you avoid the delusions of pride and arrogance and are in a better position to learn. Learn to look upon yourself as the possessor of lesser qualities and other sentient beings as possessors of greater qualities. Good qualities come to a humble person.
Pride is a severe interference in spiritual practice. By being proud and arrogant you never put yourself in the correct relationship to other sentient beings to learn from the situations you find yourself in. Also, with a lofty attitude you fall prey to anger. All it takes is one person to criticize you and you become aggressive in defense of yourself.
This is not to suggest you develop an inferiority complex, just humility. The teachings of the Kadampa Masters was to hold sentient beings more dear than yourself. The first verse says they are more precious than a wish-fulfilling jewel; the second that they have superior qualities. This method of practicing humility will greatly help your spiritual development.
