On internalizing the essence of a rule so deeply that one knows when to violate it to stay true to its intent; and remembering the obvious, instead of trying to uncover the arcane.

Also, this is not a photoshop: Acer really shipped a laptop with the trackpad above the keyboard, and I probably think about it way more often than I should.
I’d totally watch a documentary about it too. What’s the background story? How many rounds of review did it pass? What kind of culture lets this happen? How many thousands of men-hours were spent on this before it hit a store? So many questions.
“Learning becomes unlearning, […] sitting with paradox, being at peace with and navigating the tension of competing truths”
