"There was a time where a coworker had me proof their work. I went into looking over their project looking for an error in their findings, so I immediately noticed a discrepancy, but like them, I had difficulty tracing it back to their source. They said they went over their calculations and couldn't figure it out. So I went in assuming I would quickly identify their mistake, but I went over it three times. Then I realized, in my arrogance, I was simply assuming I would be able to identify quickly what they missed in their calculations. Knowing I have keen attention to detail, I realized I was missing something, but, like them, I was looking in the wrong place. Then I combed over the information they compiled. We examined it together, and we were able to determine that the error existed before they extrapolated the data from its source. Amid the research on which they based their project, two numbers had been transposed. Digging deeper, we discovered this discrepancy was the source of another problem our management had been working on. Tying our issue to theirs, we corrected the course of two projects, rather than just one. All I did was dig deeper, tracking it to its source and along with the directions, it branched out."
