Thank you for making your process public. In almost any endeavor where one compares his own process only to the observable outcome of another's process, he can believe erroneously that his (possibly superior) results are the fruit of inefficient labor and near incompetence. While I must edit repeatedly to produce reasonable prose, PG can just dash off a brilliant essay. Few know how may takes were required for a screen actor to nail a particularly difficult scene -- we just see the near-perfect result. Obviously, the same phenomenon occurs in software development. Look at how brilliantly Kevin Bourrillion (et. al., of course) designed the Guava API! [One of my favorite APIs from a design perspective] How many discussions over beverages with Josh Bloch were actually required, and to how many internal iterations at Google were we never privy?

It is only by adjusting our perceptions of the processes by which others produce quality work that we can feel good about our own abilities.
