Too small to fail

Poetry. It's what all the intelligible commentary comes down to: work within your means but also to the extent of them; don't let it slow you down any more than it has to.
As an example one of the largest banks in my country has always acted responsibly, never done anything without careful consideration, and not been involved in the whole subprime mess. Yet because of external factors (in this case bad management of other banks) their stock went down 30% in three days and they were probably on the brink of bankruptcy.
Whether you act small or not as a large company it will not insulate you from external factors that you have no control over. The best you can do is to have contingency plans, which large corporations are extremely good at.
Simple.. :-)
