Today's books video is a short piece uploaded by Josh Linkner, the author of the business book Disciplined Dreaming: A Proven System to Drive Breakthrough Creativity (Jossey-Bass, Feb. 22, 256 pages, $26.95).

The title is The Average Human Lives to 500.

Watch the video to find out what that means, but suffice it to say that -- as Linkner puts it while talking about entrepreneurs making pitches -- everyone today has a very good sense of when someone is stretching the truth.

As you share ideas, don't go out on a limb to the point where you're making stuff up, because it will erode your credibility, and all the other stuff that you say, which may be totally valid, starts to lose the authenticity that you so desperately need in this hypercompetitive world, he says.
