I second that. Maybe one more point to add abich was already hinted at in other comments. Working for company like Google allows to develop a dgree of professionalism that a start-up simply cannot. This is something you can build up on for the rest of your career.

But since you are thinking about joining a start-up, I assume you are not preparing to stay at Google until you retire, one last suggestion. Prepare for an exit strategy already basically from day one. Not to take it negative at being with Google. Just be aware that this is not your last job in your life.
