The right people will be motivated by the right words. Those who aren't right, won't hear it. If you read that and wanted to find justifications (references) on why Ellsberg was wrong, then you are too risk averse.

So, if I'm over 30, there's no time like the present!

One thing that occurred to me after posting is that now that the average life expectancy is much longer today than when some of these guys started. When Ford started his company at 40, the average life expectancy was 49.

That's average life expectancy at birth. It doesn't mean Henry Ford's life expectancy at 40 was 9 more years.

Ah good point. In 1863, it was 39.

Thanks for pointing that out.
