Thanks for sharing this, and especially the "So What" from the professor. I guess a lot of the engineers (described in the book) did feel "So What" at the end of a big project, especially one as grinding as the Eagle, but they probably found some answers when working on it -- and that's why I, as a wanna-be engineer, really enjoyed the analogy of "pinball" -- that's probably the best analogy I could find for engineers.
