Estimates Quotes

“These estimates may well be enhanced by one from F. Klein (1849-1925), the leading German mathematician of the last quarter of the nineteenth century. 'Mathematics in general is fundamentally the science of self-evident things.' ... If mathematics is indeed the science of self-evident things, mathematicians are a phenomenally stupid lot to waste the tons of good paper they do in proving the fact. Mathematics is abstract and it is hard, and any assertion that it is simple is true only in a severely technical sense—that of the modern postulational method which, as a matter of fact, was exploited by Euclid. The assumptions from which mathematics starts are simple; the rest is not.”

“Changes are not like for like, it already has an extra weight for the context switch & let’s not forget about the time already invested in the initial thought path that will no longer be valid.”

“A reality of personal productivity is that humans are not great at estimating the time required for cognitive endeavors. We’re wired to understand the demands of tangible efforts, like crafting a hand ax, or gathering edible plants. When it comes to planning pursuits for which we lack physical intuition, however, we’re guessing more than we realize, leading us to gravitate toward best-case scenarios for how long things might take. We seem to seek the thrill that comes from imagining a wildly ambitious timeline during our planning: “Wow, if I could finish four chapters this fall, I’d really be ahead of schedule!” It feels good in the moment but sets us up for scrambling and disappointment in the days that follow.

By deploying a blanket policy of doubling these initial estimates, you can counter this instinct toward unjustified optimism. The result: plans that can be completed at a more leisurely pace. The fear here, of course, is that by doubling these timelines, you’ll drastically reduce what you accomplish. But your original plans were never realistic or sustainable in the first place.”
