two general classes of great engineers: fast and slow ... Everything else I would try to have tension -- a mix of the two

To add to this, if you are one of these engineers a great career hack is to find an engineer you respect on the other end of the spectrum and partner with them.

As a "slow" engineer I make sure our key interfaces are abstractions are correct and my "fast" partner ensures that everything gets shipped and that I don't sweat the small stuff. This has lead to a lot more successful and impactful projects than I could manage on my own or with another "slow" engineer.
