To Treasure Hunters: (Part I)

If you are a junior who worries all day to impress your boss, take a deep breath! No good if you have a heart attack now.
If you are one of those playful young fellows, I'd suggest you take them, go back to them when you find life miserable and have a good laugh when you are not busy doing your research in a dark corner of the tower.
