Investments

This novel is listed as high-tech science fiction, with the following blurb:

He who believes in himself will invest in himself; he who doesn’t isn’t likely to do so. Beyond that, he who believes in his mission will invest not only in himself, but in those he deems essential to it. Investments in others aren’t necessarily made in money…nor do their payoffs always come denominated in dollars and cents.

I’m so confused.
