A single speaker uses a barbell metaphor to explain how to balance big visionary goals with day-to-day execution. The idea: put weight on both ends, not the middle. Ignore the mediocre middle ground between dreaming and doing.
In terms of the value of a North Star and kind of how to balance that with tactical execution. I'd personally like to think of it a bit like a barbell, I guess, where it's important to do a lot of work at either end of that spectrum, and I guess maybe personally enjoy doing the. The North Star stuff quite a lot. But its ultimate value is you're not going to ship it, as you said. So if you actually want to kind of keep the engines running, you have to be doing the tactical execution at the same time. And the reason I like to do both is because if you have in your mind a target of where you hope one day it will end up, everything you do tactically at the moment you're aware of how that might one day fit into the broader system that you've at least dream will maybe one day come to pass.
