I don't think I'm necessarily an example, but in high school I was generally a A- student who got As because of either inflation or I just sucked up to the teachers to give me an A. =P In college I'm more of a B student but I also haven't changed any habbits and can happily say I am able to spend an abundance of time working on my start-up and driving it forward. It helps, however, that most of my professors are leanient on allowing me to miss classes for various business reasons without reprocussions.

I can say that I hope the stat about the B student tending to have the highest net worth is accurate. =)
