To some people, success is raising a happy family. To others, it is making manager or director or executive as a cog in a Fortune 500 machine. Most of us here want to start a successful company and make a nice profit or reach a liquidity event.
I would consider myself having succeeded if I can do any or all of the following:
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.
2: Cure a major illness or create a major technological breakthrough through my own research lab.
3: Take over Equatorial Guinea.
