This likening of entrepreneurs to roller coaster riders ... I guess you just have to be a little bit mad for this gig :)

A good question someone should research is whether a thrill seeker makes a better entrepreneur than a steady individual looking for "safe" ways to increase key metrics, whatever they may be.

First you have to get to the "increase key metrics" phase...

And it usually takes quite a roller-coaster fanatic to get there in the first place.
