I suppose one can interpret my question as a bout with "existential crisis". Defining 'success' in the framework of an entire life is more of a philosophical exercise, which I'd rather not go into as of yet. "1: Make the GUI that I outlined in my first YC application, an interface intended to make the internet really easy to use for non-traditional users of computers." The latter was a great answer and it was the sort of answer I was looking for. I simply believe that there can be a greater objective in a start-up than a simple exit event. I think eBay was a success cause it had a large impact on shopping online and in fact created an entire new market; Amazon pretty much legitimized online shopping; Hotmail brought web-based email to the masses; TripAdvisor introduced reliable, user-generated opinions for all things related to travel, etc. I personally believe that a start-up's impact on society and/or business is more important than anything else.
