The blurb for Business Adventures, by John Brooks, has a quote from Bill Gates recommending it. And I think I also remember reading (???) that it is a favorite of Warren Buffett too?
In any case, my non-tycoon self has also read and liked it. And it’s now on sale at Kindle US/UK for $1.99/£0.99 respectively.
Business Adventures is on sale for $2.99 at Kindle US, but not on sale anywhere else, at least as of now…the link in the OP is still good…
