At what point do you decide that it is not worth your time? To me it seems taht at a certain point, once you've established the the margins, you grow the business to where you're no longer doing any work.......turning the business into an asset which has some nice cash flow and allows your employees to be happy.

When you're bored with the business and uninspired to do the work then I think it's time to move one. Also if you're deep in debt and not making any money I would say that's a pretty good indicator too.
