Be wary of a high “bucks-to-balls” ratio.
There are lots of people out there (mostly young men) with serious balls. The kind of chutzpa that can get a guy killed. Skydivers, race-cars, fist-fights, adrenaline junkies, drug-addicts, extreme explorers.
There are lots of people (mostly older men) with serious money. Old money, new money, self-made, inherited.
Luckily, these groups don't overlap too much. But when they do…look out! You get rockstars spending like crazy, athletes doing downright stupid [things][phelps], and entrepreneurs getting themselves killed.
Keep an eye on these types, bucks and balls mix for a dangerous cocktail.
