So "push" and "pull" as English verbs are basically opposite; and he's describing them as opposites in the previous post. But in this post he describes "push" this way:

> We are taught to do “discovery” to find their “pain points” and “problems.” So we waterboard potential customers with a series of questions to try to understand their current state... then try to surface their problems + pain points

And PULL this way:

> What are you trying to accomplish right now, or this quarter? Why this project now, vs. all the others you could prioritize? What options have you considered or tried, and what do you feel like is lacking with your existing options?

Those sound very similar to me.
