I've seen in my working life that there are cautious folks who try to think ahead (me) and folks who truly leap before looking.

Of course there's a spectrum in between.

But I've learned of these people as they ridicule me for being "risk averse" while they promise management guaranteed results on something they know nothing about. They seem to be planning on sewing themselves a parachute on the way down. (It gets ugly when the leaper is my boss.)

It may turn out that this fellow, if he wasn't suicidal, was a 'leap before you look' sort and his friends will already know this about him.
