You missed the point. I'll just clarify the intent the question here for everyone else who does:
I'm just starting my second year of college, and trying to figure out where I want my life to go. I think I was born to do startups but need to know what I can fall back to. There's a very low success rate but because of statistical bias we hear mostly from those who succeed. I want to hear the other side of the story to find out what it's really like.
If you're at all like me, you might end up being very discontented at every job you go to, especially when you see things that are obviously being done wrong, and you do not have the power to change them.
The backup plan is everyone else's primary plan. It can only help you - if you don't do anything stupid. (For example, don't take on any personal debt, and avoid non-competes / restrictive covenants.) Starting your own venture is a showcase for creativity, skill, wit and hard work; all things that will help you in a future career.
The one problem I've had is that some jobs are literally beneath you once you've started a company - people can be afraid to hire you. But that's not really an obstacle as much as a platform.
