>Ironic that this chapter fails to get its own point

You're not making your case very well.

The two passages you excerpt are about useless vagueness in "success" books/articles. You are completely missing the point of the passage about "success in jumping," which is that "success" books and articles of the time (around 1908), are vague pump-you-up bullshit that any idiot could write.

Chesterton never argues that all "rich people are avaricious." Chesterton believes money and prestige are not really worth putting a person's main passion and energy into, which is what the Success books (circa 1908) seem to advocate. This essay is mainly a criticism of particular Success books and the Success idea; it is NOT an essay about getting rich or about limiting beliefs. It is also a criticism of the worship of rich and powerful men.

Chesterton never "declare[s] that limitations of the self are simply not worth considering."

You don't seem to realize that the this essay goes much deeper that criticizing how to be successful, but the very idea of "success" itself.
