You need to be really really introspective. I know a lot of CEO's that were really happy as the number two in their previous company. As the COO, or CFO or whatever and they are miserable as CEO's. I have hired a number of folks who will tell you they want to be in start ups, who desperately want this to be the right path for them and they should be working at Bank of America. There is a very different support structure that comes with a big company and if your mind set is how to I extract the greatest value for me from this company you are going to have a hard time with a start up.
