It must be called the ego

Have you given up trying things over and over and they don't work? Like you've been beating your head on the brick wall, but you don't want to give up. So a good way to approach this problem is to go back to the original source of information and hey it is all revealed so easily! How is it that we sometimes think that we know better than the person who has done this stuff before you?? Ridiculous stuff huh? It must be called the ego!
