Wisdom of an anonymous Bishop

I have a friend at work who is pretty funny. we have lunch together everyday. He is a serious game player with a high rank among gamers in Canada and call himself a Bishop.Today he told me something really wise. He told me that he couldn't earn one achievement in latest Call of Duty game in XBox and last night he dreamed about it. He said "Imagine how upset I was that I dreamed about it." Then he continued " you should make yourself fake challenges in life so that real ones have to stay in line".
