A group I've encountered that this could help are those without tenacity. I have smart friends who are hugely into tech who somehow remained unemployable even during the boom times in that industry.

I try and try to push them towards opportunities but they argue 'I just have no natural talent for that' and stop before they even get started.

Eg. they tried programming for 3 days, still hadn't fully groked it (because no one does in that amount of time!) and gave up with the above line. Somewhat frustrating to deal with as a friend and also clear cut in what's holding them back as an outside observer: they simply aren't aggressively fighting internal and external demons that tell them they aren't good enough for something. The mere suggestion that you can't possibly do something should fill you with burning determination and it's a positive emotion to feel in that scenario but they seem to just roll over.
