The book Moby Dick implies that if you fully complete everything you set out to do then your visions are not grand enough. The narrator Ishmael in the chapter on Cetology says, "God keep me from ever completing anything."
The chapter was referring to the Cologne Cathedral in Germany, which was still incomplete at the time of the writing of Moby Dick, but eventually, after over 400 years of remaining in an incomplete state, was finally finished in 1880.
I thought that was an interesting fact.
