it was really more of a reference to your post (I’m paraphrasing here, so please excuse my not getting it exactly right). Something about weight lifting and adding more weight eventually you’ll be able to bear the weight of the world...
Bobby Jack made a bet with his boss (I believe it was his boss anyhow) that he could lift a a full grown bull by starting out while it was a calf and lifting it once every day - thus conditioning his body to be able to lift more and more weight gradually. Eventually the bull came to like the attention and was also conditioned to the daily lift. Regardless, there was a point where the bull grew too big and Bobby Jack could no longer lift him no matter how hard he tried. I believe there is a moral to the story in there somewhere... oh yes, eventually no matter how much you try some things are insurmountable (not everything, but some things), something about pride, etc...
That is what the media attempts to do - make the climb insurmountable. In this case, Sarah may just prove them wrong.
Good analogy. Worth checking out;)
