The Dimension of Focus
After finishing a paper, Einstein and his assistant could find only one paper clip in his office to hold the pages together. Unfortunately, it was bent out of shape and impossible to use. They searched the desk for something to use as a tool to straighten the clip and found a full box of paper clips in one drawer. Instead of taking one of those clips, Einstein used one of those clips as a tool to straighten out the bent clip. The assistant asked why he didn't just use one of the fresh clips. Einstein answered, "Once I am set on a goal it becomes difficult to deflect me."
