Does james truslow adams undercut his argument about the american dream when he qualifies the opportunity it offers by adding “according to ability or achievement”? or is he just being realistic?

I believe he is just being realistic. He is arguing that the American Dream can indeed offer opportunities that are not available to people anywhere else. However, this does not mean that everyone has the chance to become equally successful and wealthy. Your chances and your success are going to be determined by factors such as ability, or achievement. It is a more realistic view of what the "dream" actually looks like in practice.

subject: why anyone can be a genius.

occasion: moving forward in life.

audience: average person

purpose: to push you further in life

speaker: many famous geniuses.

here is the poem:

here is thy, and here is thee, genius is for what he can be.

poem is a matter of rhyme, but like ben frank said, life is a matter of time.

we have great inventors such as thomas edison, who said, "genius is one percent inspiration and 99% perspiration." no, no perspiration as what comes from your skeleton.

we have great minds, from places of all kinds, such as yu kaw la chi tie, (now im switching languages because yu kaw was japanese.)

てちハラスイヒイス, てちラスイヒイス

てちのちみスイヒイス.

you are a genius, well not yet, but you are capable, and that is a bet.
