This idea, making future consequences (positive or negative) of present choices more vivid and real is something I learned from this LessWrong article[1]. I think it will appeal more to this audience than _The Secret_.
Yeah, not to judge a book by it's cover, but everything about "The Secret" screams new-agey superstitious bullshit (redundant?). Positive psychology does seem to have some common sense things going for it (ie, if you think something is impossible, it probably is, for you), but there are better books out there (cf "The Happiness Advantage" by Shawn Achor; he also did a TED talk that sums up some of the themes nicely: http://www.ted.com/talks/shawn_achor_the_happy_secret_to_bet...)
I absolutely hate messianic-style writing.
