I'm always suspicious of founders that want an exit. Am I really to believe they think they're doing their life's work and trying to save the world if they want to be done with it in a few years? Do they really think of it as their baby if they'd happily sell it and never see it again?

If I was a V.C., I would dismiss any founder that answered the "what is your exit strategy?" question with anything other than a middle finger. A good V.C. would see it as the V.C.'s job to convince the founder to sell at the right time.
