There are times in my life where I'd have read these, been really deeply impacted by them, and picked up a new mantra or 2 for a few weeks. It's like "Get a plan, execute it violently, do it today".
If you're in a time and place where you're motivated to "move fast and break things", I think you'll nod along with Boris' post.
But it's so general and high level, the only meaning you get from it depends entirely on your own personal attitude and examples that you throw at it.
The obvious pro angle is: "yeah, understand stuff well, biased for action, act urgently, yeah!" and competent, motivated, currently-in-the-zone people will spring into action. (But they would have done anyway, because they're already motivated and in the zone).
The obvious against angle is "uuuh, last week you said we needed to be goal oriented, and now you're telling us to go and learn a bunch before we even know why/what we're learning? And I've learnt a bunch of stuff, but you're telling me it's not right because it doesn't fit within this framework you just invented that you're now telling me I absolutely have to follow and you're my manager so I have no choice?"
I'm not totally hating on this, there's a time and a place for it and I've found it very motivating at times where I was already thoroughly motivated, but I think it's also useful to recognise that it comes across as self-serving platitudes for a lot of people who aren't already in that kinda zone.
