I have a hard time not reading this as a "pull yourself up by your bootstraps".
That's just my experience, YMMV.
The vast majority of people like that aren't (and don't) getting into Stanford, period, because impressive-to-admissions-committee folks are usually children of other impressive people (not always, usually). I don't think it's possible to interpret this as anything but "pulling yourself up by your bootstraps".
So, maybe things are different now.
