The downfalls of arrogance
Anyone who is characteristically arrogant might feel a sort of overinflated pride in their hollow boastings and know-it-all attitude. This will no doubt impede their ability to improve and advance themselves as a human being. In this game, an arrogant person will eventually lose the support of his allies and invite bitter feelings of resentment instead. He will fail to learn new things and won't be able to interact successfully with the people in his environment due to the stubborn way he holds fast to his arrogance.
In the hopes of getting ahead in the world and keeping your social network intact, it would be best to recognize when and why you're coming across as being arrogant. Once you've identified the triggers that set off your arrogance, it's time to gradually start toning it down and making an effort to drop the pretense of being all knowledgeable. That way, when you are approached with a better method of doing something, or are offered to be taught new things, you'll happily embrace the opportunity to progress in life.
